Although pytorch-nightly should in theory be faster, it is currently causing increased memory usage and slower iterations: https://github.com/lstein/stable-diffusion/pull/283#issuecomment-1234784885 This changes the environment-mac.yaml file back to the regular pytorch channel and moves the `transformers` dep into pip for now (since it cannot be satisfied until tokenizers>=0.11 is built for Python 3.10). * Specify versions for Pip packages as well. commitd0d95d3a2aAuthor: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 14:10:31 2022 -0400 make initimg appear in web log commitb90a215000Merge:1eee8116270e31Author: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 13:47:15 2022 -0400 Merge branch 'prixt-seamless' into development commit6270e313b8Author: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 13:46:29 2022 -0400 add credit to prixt for seamless circular tiling commita01b7bdc40Merge:1eee8119d88abeAuthor: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 13:43:04 2022 -0400 add web interface for seamless option commit1eee8111b9Merge:64eca42fb857f0Author: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 12:33:39 2022 -0400 Merge branch 'development' of github.com:lstein/stable-diffusion into development commit64eca42610Merge:9130ad721a1f68Author: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 12:33:05 2022 -0400 Merge branch 'main' into development * brings in small documentation fixes that were added directly to main during release tweaking. commitfb857f05baAuthor: Lincoln Stein <lincoln.stein@gmail.com> Date: Sat Sep 3 12:07:07 2022 -0400 fix typo in docs commit9d88abe2eaAuthor: prixt <paraxite@naver.com> Date: Sat Sep 3 22:42:16 2022 +0900 fixed typo commita61e49bc97Author: prixt <paraxite@naver.com> Date: Sat Sep 3 22:39:35 2022 +0900 * Removed unnecessary code * Added description about --seamless commit02bee4fdb1Author: prixt <paraxite@naver.com> Date: Sat Sep 3 16:08:03 2022 +0900 added --seamless tag logging to normalize_prompt commitd922b53c26Author: prixt <paraxite@naver.com> Date: Sat Sep 3 15:13:31 2022 +0900 added seamless tiling mode and commands

This is a fork of CompVis/stable-diffusion, the wonderful open source
|
||||
text-to-image generator. This fork supports:
|
||||
# **Stable Diffusion Dream Script**
|
||||
|
||||
1. An interactive command-line interface that accepts the same prompt
|
||||
and switches as the Discord bot.
|
||||
This is a fork of
|
||||
[CompVis/stable-diffusion](https://github.com/CompVis/stable-diffusion),
|
||||
the open source text-to-image generator. It provides a streamlined
|
||||
process with various new features and options to aid the image
|
||||
generation process. It runs on Windows, Mac and Linux machines,
|
||||
and runs on GPU cards with as little as 4 GB or RAM.
|
||||
|
||||
2. A basic Web interface that allows you to run a local web server for
|
||||
generating images in your browser.
|
||||
_Note: This fork is rapidly evolving. Please use the
|
||||
[Issues](https://github.com/lstein/stable-diffusion/issues) tab to
|
||||
report bugs and make feature requests. Be sure to use the provided
|
||||
templates. They will help aid diagnose issues faster._
|
||||
|
||||
3. Support for img2img in which you provide a seed image to guide the
|
||||
image creation. (inpainting & masking coming soon)
|
||||
# **Table of Contents**
|
||||
|
||||
4. A notebook for running the code on Google Colab.
|
||||
|
||||
5. Upscaling and face fixing using the optional ESRGAN and GFPGAN
|
||||
packages.
|
||||
|
||||
6. Weighted subprompts for prompt tuning.
|
||||
|
||||
7. [Image variations](VARIATIONS.md) which allow you to systematically
|
||||
generate variations of an image you like and combine two or more
|
||||
images together to combine the best features of both.
|
||||
|
||||
8. Textual inversion for customization of the prompt language and images.
|
||||
|
||||
8. ...and more!
|
||||
|
||||
This fork is rapidly evolving, so use the Issues panel to report bugs
|
||||
and make feature requests, and check back periodically for
|
||||
improvements and bug fixes.

# Installation
|
||||
|
||||
## Interactive command-line interface similar to the Discord bot
|
||||
This fork is supported across multiple platforms. You can find individual installation instructions below.
|
||||
|
||||
The _dream.py_ script, located in scripts/dream.py,
|
||||
provides an interactive interface to image generation similar to
|
||||
the "dream mothership" bot that Stable AI provided on its Discord
|
||||
server. Unlike the txt2img.py and img2img.py scripts provided in the
|
||||
original CompViz/stable-diffusion source code repository, the
|
||||
time-consuming initialization of the AI model
|
||||
initialization only happens once. After that image generation
|
||||
from the command-line interface is very fast.
|
||||
- ## [Linux](docs/installation/INSTALL_LINUX.md)
|
||||
- ## [Windows](docs/installation/INSTALL_WINDOWS.md)
|
||||
- ## [Macintosh](docs/installation/INSTALL_MAC.md)
|
||||
|
||||
The script uses the readline library to allow for in-line editing,
|
||||
command history (up and down arrows), autocompletion, and more. To help
|
||||
keep track of which prompts generated which images, the script writes a
|
||||
log file of image names and prompts to the selected output directory.
|
||||
In addition, as of version 1.02, it also writes the prompt into the PNG
|
||||
file's metadata where it can be retrieved using scripts/images2prompt.py
|
||||
## **Hardware Requirements**
|
||||
|
||||
The script is confirmed to work on Linux and Windows systems. It should
|
||||
work on MacOSX as well, but this is not confirmed. Note that this script
|
||||
runs from the command-line (CMD or Terminal window), and does not have a GUI.
|
||||
**System**
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/dream.py
|
||||
* Initializing, be patient...
|
||||
Loading model from models/ldm/text2img-large/model.ckpt
|
||||
(...more initialization messages...)
|
||||
You wil need one of the following:
|
||||
|
||||
* Initialization done! Awaiting your command...

**Disk**
|
||||
|
||||
The dream> prompt's arguments are pretty much identical to those used
|
||||
in the Discord bot, except you don't need to type "!dream" (it doesn't
|
||||
hurt if you do). A significant change is that creation of individual
|
||||
images is now the default unless --grid (-g) is given. For backward
|
||||
compatibility, the -i switch is recognized. For command-line help
|
||||
type -h (or --help) at the dream> prompt.
|
||||
|
||||
The script itself also recognizes a series of command-line switches
|
||||
that will change important global defaults, such as the directory for
|
||||
image outputs and the location of the model weight files.
|
||||
|
||||
## Image-to-Image
|
||||
|
||||
This script also provides an img2img feature that lets you seed your
|
||||
creations with a drawing or photo. This is a really cool feature that tells
|
||||
stable diffusion to build the prompt on top of the image you provide, preserving
|
||||
the original's basic shape and layout. To use it, provide the --init_img
|
||||
option as shown here:
|
||||
|
||||
```
|
||||
dream> "waterfall and rainbow" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
|
||||
```
|
||||
|
||||
The --init_img (-I) option gives the path to the seed picture. --strength (-f) controls how much
|
||||
the original will be modified, ranging from 0.0 (keep the original intact), to 1.0 (ignore the original
|
||||
completely). The default is 0.75, and ranges from 0.25-0.75 give interesting results.
|
||||
|
||||
You may also pass a -v<count> option to generate count variants on the original image. This is done by
|
||||
passing the first generated image back into img2img the requested number of times. It generates interesting
|
||||
variants.
|
||||
|
||||
## GFPGAN and Real-ESRGAN Support
|
||||
|
||||
The script also provides the ability to do face restoration and
|
||||
upscaling with the help of GFPGAN and Real-ESRGAN respectively.
|
||||
|
||||
To use the ability, clone the **[GFPGAN
|
||||
repository](https://github.com/TencentARC/GFPGAN)** and follow their
|
||||
installation instructions. By default, we expect GFPGAN to be
|
||||
installed in a 'GFPGAN' sibling directory. Be sure that the `"ldm"`
|
||||
conda environment is active as you install GFPGAN.
|
||||
|
||||
You can use the `--gfpgan_dir` argument with `dream.py` to set a
|
||||
custom path to your GFPGAN directory. _There are other GFPGAN related
|
||||
boot arguments if you wish to customize further._
|
||||
|
||||
You can install **Real-ESRGAN** by typing the following command.
|
||||
|
||||
```
|
||||
pip install realesrgan
|
||||
```
|
||||
|
||||
**Note: Internet connection needed:**
|
||||
Users whose GPU machines are isolated from the Internet (e.g. on a
|
||||
University cluster) should be aware that the first time you run
|
||||
dream.py with GFPGAN and Real-ESRGAN turned on, it will try to
|
||||
download model files from the Internet. To rectify this, you may run
|
||||
`python3 scripts/preload_models.py` after you have installed GFPGAN
|
||||
and all its dependencies.
|
||||
|
||||
**Usage**
|
||||
|
||||
You will now have access to two new prompt arguments.
|
||||
|
||||
**Upscaling**
|
||||
|
||||
`-U : <upscaling_factor> <upscaling_strength>`
|
||||
|
||||
The upscaling prompt argument takes two values. The first value is a
|
||||
scaling factor and should be set to either `2` or `4` only. This will
|
||||
either scale the image 2x or 4x respectively using different models.
|
||||
|
||||
You can set the scaling stength between `0` and `1.0` to control
|
||||
intensity of the of the scaling. This is handy because AI upscalers
|
||||
generally tend to smooth out texture details. If you wish to retain
|
||||
some of those for natural looking results, we recommend using values
|
||||
between `0.5 to 0.8`.
|
||||
|
||||
If you do not explicitly specify an upscaling_strength, it will
|
||||
default to 0.75.
|
||||
|
||||
**Face Restoration**
|
||||
|
||||
`-G : <gfpgan_strength>`
|
||||
|
||||
This prompt argument controls the strength of the face restoration
|
||||
that is being applied. Similar to upscaling, values between `0.5 to 0.8` are recommended.
|
||||
|
||||
You can use either one or both without any conflicts. In cases where
|
||||
you use both, the image will be first upscaled and then the face
|
||||
restoration process will be executed to ensure you get the highest
|
||||
quality facial features.
|
||||
|
||||
`--save_orig`
|
||||
|
||||
When you use either `-U` or `-G`, the final result you get is upscaled
|
||||
or face modified. If you want to save the original Stable Diffusion
|
||||
generation, you can use the `-save_orig` prompt argument to save the
|
||||
original unaffected version too.
|
||||
|
||||
**Example Usage**
|
||||
|
||||
```
|
||||
dream > superman dancing with a panda bear -U 2 0.6 -G 0.4
|
||||
```
|
||||
|
||||
This also works with img2img:
|
||||
|
||||
```
|
||||
dream> a man wearing a pineapple hat -I path/to/your/file.png -U 2 0.5 -G 0.6
|
||||
```
|
||||
- At least 6 GB of free disk space for the machine learning model, Python, and all its dependencies.
|
||||
|
||||
**Note**
|
||||
|
||||
GFPGAN and Real-ESRGAN are both memory intensive. In order to avoid
|
||||
crashes and memory overloads during the Stable Diffusion process,
|
||||
these effects are applied after Stable Diffusion has completed its
|
||||
work.
|
||||
If you are have a Nvidia 10xx series card (e.g. the 1080ti), please
|
||||
run the dream script in full-precision mode as shown below.
|
||||
|
||||
In single image generations, you will see the output right away but
|
||||
when you are using multiple iterations, the images will first be
|
||||
generated and then upscaled and face restored after that process is
|
||||
complete. While the image generation is taking place, you will still
|
||||
be able to preview the base images.
|
||||
Similarly, specify full-precision mode on Apple M1 hardware.
|
||||
|
||||
If you wish to stop during the image generation but want to upscale or
|
||||
face restore a particular generated image, pass it again with the same
|
||||
prompt and generated seed along with the `-U` and `-G` prompt
|
||||
arguments to perform those actions.

## Barebones Web Server
|
||||
|
||||
As of version 1.10, this distribution comes with a bare bones web
|
||||
server (see screenshot). To use it, run the _dream.py_ script by
|
||||
adding the **--web** option.
|
||||
To run in full-precision mode, start `dream.py` with the
|
||||
`--full_precision` flag:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py --web
|
||||
(ldm) ~/stable-diffusion$ python scripts/dream.py --full_precision
|
||||
```
|
||||
|
||||
You can then connect to the server by pointing your web browser at
|
||||
http://localhost:9090, or to the network name or IP address of the server.

# Features
|
||||
|
||||
Kudos to [Tesseract Cat](https://github.com/TesseractCat) for
|
||||
contributing this code, and to [dagf2101](https://github.com/dagf2101)
|
||||
for refining it.
|
||||
## **Major Features**
|
||||
|
||||
|
||||
- ## [Interactive Command Line Interface](docs/features/CLI.md)
|
||||
|
||||
## Reading Prompts from a File
|
||||
- ## [Image To Image](docs/features/IMG2IMG.md)
|
||||
|
||||
You can automate dream.py by providing a text file with the prompts
|
||||
you want to run, one line per prompt. The text file must be composed
|
||||
with a text editor (e.g. Notepad) and not a word processor. Each line
|
||||
should look like what you would type at the dream> prompt:
|
||||
- ## [Inpainting Support](docs/features/INPAINTING.md)
|
||||
|
||||
```
|
||||
a beautiful sunny day in the park, children playing -n4 -C10
|
||||
stormy weather on a mountain top, goats grazing -s100
|
||||
innovative packaging for a squid's dinner -S137038382
|
||||
```
|
||||
- ## [GFPGAN and Real-ESRGAN Support](docs/features/UPSCALE.md)
|
||||
|
||||
Then pass this file's name to dream.py when you invoke it:
|
||||
- ## [Seamless Tiling](docs/features/OTHER.md#seamless-tiling)
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py --from_file "path/to/prompts.txt"
|
||||
```
|
||||
- ## [Google Colab](docs/features/OTHER.md#google-colab)
|
||||
|
||||
You may read a series of prompts from standard input by providing a filename of "-":
|
||||
- ## [Web Server](docs/features/WEB.md)
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ echo "a beautiful day" | python3 scripts/dream.py --from_file -
|
||||
```
|
||||
- ## [Reading Prompts From File](docs/features/OTHER.md#reading-prompts-from-a-file)
|
||||
|
||||
## Shortcut for reusing seeds from the previous command
|
||||
- ## [Shortcut: Reusing Seeds](docs/features/OTHER.md#shortcuts-reusing-seeds)
|
||||
|
||||
Since it is so common to reuse seeds while refining a prompt, there is
|
||||
now a shortcut as of version 1.11. Provide a **-S** (or **--seed**)
|
||||
switch of -1 to use the seed of the most recent image generated. If
|
||||
you produced multiple images with the **-n** switch, then you can go
|
||||
back further using -2, -3, etc. up to the first image generated by the
|
||||
previous command. Sorry, but you can't go back further than one
|
||||
command.
|
||||
- ## [Weighted Prompts](docs/features/OTHER.md#weighted-prompts)
|
||||
|
||||
Here's an example of using this to do a quick refinement. It also
|
||||
illustrates using the new **-G** switch to turn on upscaling and
|
||||
face enhancement (see previous section):
|
||||
- ## [Variations](docs/features/VARIATIONS.md)
|
||||
|
||||
```
|
||||
dream> a cute child playing hopscotch -G0.5

|
||||
- ## [Personalizing Text-to-Image Generation](docs/features/TEXTUAL_INVERSION.md)
|
||||
|
||||
# I wonder what it will look like if I bump up the steps and set facial enhancement to full strength?

|
||||
```
|
||||
- ## [Simplified API for text to image generation](docs/features/OTHER.md#simplified-api)
|
||||
|
||||
## Weighted Prompts
|
||||
## **Other Features**
|
||||
|
||||
You may weight different sections of the prompt to tell the sampler to attach different levels of
|
||||
priority to them, by adding :(number) to the end of the section you wish to up- or downweight.
|
||||
For example consider this prompt:
|
||||
- ### [Creating Transparent Regions for Inpainting](docs/features/INPAINTING.md#creating-transparent-regions-for-inpainting)
|
||||
|
||||
```
|
||||
tabby cat:0.25 white duck:0.75 hybrid
|
||||
```
|
||||
|
||||
This will tell the sampler to invest 25% of its effort on the tabby
|
||||
cat aspect of the image and 75% on the white duck aspect
|
||||
(surprisingly, this example actually works). The prompt weights can
|
||||
use any combination of integers and floating point numbers, and they
|
||||
do not need to add up to 1.
|
||||
|
||||
## Personalizing Text-to-Image Generation
|
||||
|
||||
You may personalize the generated images to provide your own styles or objects by training a new LDM checkpoint
|
||||
and introducing a new vocabulary to the fixed model.
|
||||
|
||||
To train, prepare a folder that contains images sized at 512x512 and execute the following:
|
||||
|
||||
|
||||
WINDOWS: As the default backend is not available on Windows, if you're using that platform, set the environment variable `PL_TORCH_DISTRIBUTED_BACKEND=gloo`
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./main.py --base ./configs/stable-diffusion/v1-finetune.yaml \
|
||||
-t \
|
||||
--actual_resume ./models/ldm/stable-diffusion-v1/model.ckpt \
|
||||
-n my_cat \
|
||||
--gpus 0, \
|
||||
--data_root D:/textual-inversion/my_cat \
|
||||
--init_word 'cat'
|
||||
```
|
||||
|
||||
During the training process, files will be created in /logs/[project][time][project]/
|
||||
where you can see the process.
|
||||
|
||||
conditioning\* contains the training prompts
|
||||
inputs, reconstruction the input images for the training epoch
|
||||
samples, samples scaled for a sample of the prompt and one with the init word provided
|
||||
|
||||
On a RTX3090, the process for SD will take ~1h @1.6 iterations/sec.
|
||||
|
||||
Note: According to the associated paper, the optimal number of images
|
||||
is 3-5. Your model may not converge if you use more images than that.
|
||||
|
||||
Training will run indefinately, but you may wish to stop it before the
|
||||
heat death of the universe, when you find a low loss epoch or around
|
||||
~5000 iterations.
|
||||
|
||||
Once the model is trained, specify the trained .pt file when starting
|
||||
dream using
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/dream.py --embedding_path /path/to/embedding.pt --full_precision
|
||||
```
|
||||
|
||||
Then, to utilize your subject at the dream prompt
|
||||
|
||||
```
|
||||
dream> "a photo of *"
|
||||
```
|
||||
|
||||
this also works with image2image
|
||||
|
||||
```
|
||||
dream> "waterfall and rainbow in the style of *" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
|
||||
```
|
||||
|
||||
It's also possible to train multiple tokens (modify the placeholder string in configs/stable-diffusion/v1-finetune.yaml) and combine LDM checkpoints using:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/merge_embeddings.py \
|
||||
--manager_ckpts /path/to/first/embedding.pt /path/to/second/embedding.pt [...] \
|
||||
--output_path /path/to/output/embedding.pt
|
||||
```

# Installation
|
||||
|
||||
There are separate installation walkthroughs for [Linux](#linux), [Windows](#windows) and [Macintosh](#Macintosh)
|
||||
|
||||
## Linux
|
||||
|
||||
1. You will need to install the following prerequisites if they are not already available. Use your
|
||||
operating system's preferred installer
|
||||
|
||||
- Python (version 3.8.5 recommended; higher may work)
|
||||
- git
|
||||
|
||||
2. Install the Python Anaconda environment manager.
|
||||
|
||||
```
|
||||
~$ wget https://repo.anaconda.com/archive/Anaconda3-2022.05-Linux-x86_64.sh
|
||||
~$ chmod +x Anaconda3-2022.05-Linux-x86_64.sh
|
||||
~$ ./Anaconda3-2022.05-Linux-x86_64.sh
|
||||
```
|
||||
|
||||
After installing anaconda, you should log out of your system and log back in. If the installation
|
||||
worked, your command prompt will be prefixed by the name of the current anaconda environment, "(base)".
|
||||
|
||||
3. Copy the stable-diffusion source code from GitHub:
|
||||
|
||||
```
|
||||
(base) ~$ git clone https://github.com/lstein/stable-diffusion.git
|
||||
```
|
||||
|
||||
This will create stable-diffusion folder where you will follow the rest of the steps.
|
||||
|
||||
4. Enter the newly-created stable-diffusion folder. From this step forward make sure that you are working in the stable-diffusion directory!
|
||||
|
||||
```
|
||||
(base) ~$ cd stable-diffusion
|
||||
(base) ~/stable-diffusion$
|
||||
```
|
||||
|
||||
5. Use anaconda to copy necessary python packages, create a new python environment named "ldm",
|
||||
and activate the environment.
|
||||
|
||||
```
|
||||
(base) ~/stable-diffusion$ conda env create -f environment.yaml
|
||||
(base) ~/stable-diffusion$ conda activate ldm
|
||||
(ldm) ~/stable-diffusion$
|
||||
```
|
||||
|
||||
After these steps, your command prompt will be prefixed by "(ldm)" as shown above.
|
||||
|
||||
6. Load a couple of small machine-learning models required by stable diffusion:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/preload_models.py
|
||||
```
|
||||
|
||||
Note that this step is necessary because I modified the original
|
||||
just-in-time model loading scheme to allow the script to work on GPU
|
||||
machines that are not internet connected. See [Workaround for machines with limited internet connectivity](#workaround-for-machines-with-limited-internet-connectivity)
|
||||
|
||||
7. Now you need to install the weights for the stable diffusion model.
|
||||
|
||||
For running with the released weights, you will first need to set up an acount with Hugging Face (https://huggingface.co).
|
||||
Use your credentials to log in, and then point your browser at https://huggingface.co/CompVis/stable-diffusion-v-1-4-original.
|
||||
You may be asked to sign a license agreement at this point.
|
||||
|
||||
Click on "Files and versions" near the top of the page, and then click on the file named "sd-v1-4.ckpt". You'll be taken
|
||||
to a page that prompts you to click the "download" link. Save the file somewhere safe on your local machine.
|
||||
|
||||
Now run the following commands from within the stable-diffusion directory. This will create a symbolic
|
||||
link from the stable-diffusion model.ckpt file, to the true location of the sd-v1-4.ckpt file.
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ mkdir -p models/ldm/stable-diffusion-v1
|
||||
(ldm) ~/stable-diffusion$ ln -sf /path/to/sd-v1-4.ckpt models/ldm/stable-diffusion-v1/model.ckpt
|
||||
```
|
||||
|
||||
8. Start generating images!
|
||||
|
||||
```
|
||||
# for the pre-release weights use the -l or --liaon400m switch
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py -l
|
||||
|
||||
# for the post-release weights do not use the switch
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py
|
||||
|
||||
# for additional configuration switches and arguments, use -h or --help
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py -h
|
||||
```
|
||||
|
||||
9. Subsequently, to relaunch the script, be sure to run "conda activate ldm" (step 5, second command), enter the "stable-diffusion"
|
||||
directory, and then launch the dream script (step 8). If you forget to activate the ldm environment, the script will fail with multiple ModuleNotFound errors.
|
||||
|
||||
### Updating to newer versions of the script
|
||||
|
||||
This distribution is changing rapidly. If you used the "git clone" method (step 5) to download the stable-diffusion directory, then to update to the latest and greatest version, launch the Anaconda window, enter "stable-diffusion", and type:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ git pull
|
||||
```
|
||||
|
||||
This will bring your local copy into sync with the remote one.
|
||||
|
||||
## Windows
|
||||
|
||||
### Notebook install (semi-automated)
|
||||
|
||||
We have a
|
||||
[Jupyter notebook](https://github.com/lstein/stable-diffusion/blob/main/Stable-Diffusion-local-Windows.ipynb)
|
||||
with cell-by-cell installation steps. It will download the code in this repo as
|
||||
one of the steps, so instead of cloning this repo, simply download the notebook
|
||||
from the link above and load it up in VSCode (with the
|
||||
appropriate extensions installed)/Jupyter/JupyterLab and start running the cells one-by-one.
|
||||
|
||||
Note that you will need NVIDIA drivers, Python 3.10, and Git installed
|
||||
beforehand - simplified
|
||||
[step-by-step instructions](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
are available in the wiki (you'll only need steps 1, 2, & 3 ).
|
||||
|
||||
### Manual installs
|
||||
|
||||
#### pip
|
||||
|
||||
See
|
||||
[Easy-peasy Windows install](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
in the wiki
|
||||
|
||||
#### Conda
|
||||
|
||||
1. Install Anaconda3 (miniconda3 version) from here: https://docs.anaconda.com/anaconda/install/windows/
|
||||
|
||||
2. Install Git from here: https://git-scm.com/download/win
|
||||
|
||||
3. Launch Anaconda from the Windows Start menu. This will bring up a command window. Type all the remaining commands in this window.
|
||||
|
||||
4. Run the command:
|
||||
|
||||
```
|
||||
git clone https://github.com/lstein/stable-diffusion.git
|
||||
```
|
||||
|
||||
This will create stable-diffusion folder where you will follow the rest of the steps.
|
||||
|
||||
5. Enter the newly-created stable-diffusion folder. From this step forward make sure that you are working in the stable-diffusion directory!
|
||||
|
||||
```
|
||||
cd stable-diffusion
|
||||
```
|
||||
|
||||
6. Run the following two commands:
|
||||
|
||||
```
|
||||
conda env create -f environment.yaml (step 6a)
|
||||
conda activate ldm (step 6b)
|
||||
```
|
||||
|
||||
This will install all python requirements and activate the "ldm" environment which sets PATH and other environment variables properly.
|
||||
|
||||
7. Run the command:
|
||||
|
||||
```
|
||||
python scripts\preload_models.py
|
||||
```
|
||||
|
||||
This installs several machine learning models that stable diffusion
|
||||
requires. (Note that this step is required. I created it because some people
|
||||
are using GPU systems that are behind a firewall and the models can't be
|
||||
downloaded just-in-time)
|
||||
|
||||
8. Now you need to install the weights for the big stable diffusion model.
|
||||
|
||||
For running with the released weights, you will first need to set up
|
||||
an acount with Hugging Face (https://huggingface.co). Use your
|
||||
credentials to log in, and then point your browser at
|
||||
https://huggingface.co/CompVis/stable-diffusion-v-1-4-original. You
|
||||
may be asked to sign a license agreement at this point.
|
||||
|
||||
Click on "Files and versions" near the top of the page, and then click
|
||||
on the file named "sd-v1-4.ckpt". You'll be taken to a page that
|
||||
prompts you to click the "download" link. Now save the file somewhere
|
||||
safe on your local machine. The weight file is >4 GB in size, so
|
||||
downloading may take a while.
|
||||
|
||||
Now run the following commands from **within the stable-diffusion
|
||||
directory** to copy the weights file to the right place:
|
||||
|
||||
```
|
||||
mkdir -p models\ldm\stable-diffusion-v1
|
||||
copy C:\path\to\sd-v1-4.ckpt models\ldm\stable-diffusion-v1\model.ckpt
|
||||
```
|
||||
|
||||
Please replace "C:\path\to\sd-v1.4.ckpt" with the correct path to wherever
|
||||
you stashed this file. If you prefer not to copy or move the .ckpt file,
|
||||
you may instead create a shortcut to it from within
|
||||
"models\ldm\stable-diffusion-v1\".
|
||||
|
||||
9. Start generating images!
|
||||
|
||||
```
|
||||
# for the pre-release weights
|
||||
python scripts\dream.py -l
|
||||
|
||||
# for the post-release weights
|
||||
python scripts\dream.py
|
||||
```
|
||||
|
||||
10. Subsequently, to relaunch the script, first activate the Anaconda
|
||||
command window (step 3), enter the stable-diffusion directory (step 5,
|
||||
"cd \path\to\stable-diffusion"), run "conda activate ldm" (step 6b),
|
||||
and then launch the dream script (step 9).
|
||||
|
||||
**Note:** Tildebyte has written an alternative ["Easy peasy Windows
|
||||
install"](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
which uses the Windows Powershell and pew. If you are having trouble
|
||||
with Anaconda on Windows, give this a try (or try it first!)
|
||||
|
||||
### Updating to newer versions of the script
|
||||
|
||||
This distribution is changing rapidly. If you used the "git clone"
|
||||
method (step 5) to download the stable-diffusion directory, then to
|
||||
update to the latest and greatest version, launch the Anaconda window,
|
||||
enter "stable-diffusion", and type:
|
||||
|
||||
```
|
||||
git pull
|
||||
```
|
||||
|
||||
This will bring your local copy into sync with the remote one.

# Simplified API for text to image generation
|
||||
|
||||
For programmers who wish to incorporate stable-diffusion into other
|
||||
products, this repository includes a simplified API for text to image
|
||||
generation, which lets you create images from a prompt in just three
|
||||
lines of code:
|
||||
|
||||
```
|
||||
from ldm.simplet2i import T2I
|
||||
model = T2I()
|
||||
outputs = model.txt2img("a unicorn in manhattan")
|
||||
```
|
||||
|
||||
Outputs is a list of lists in the format [[filename1,seed1],[filename2,seed2]...]
|
||||
Please see ldm/simplet2i.py for more information. A set of example scripts is
|
||||
coming RSN.

||||
|
||||
# Workaround for machines with limited internet connectivity
|
||||
|
||||
My development machine is a GPU node in a high-performance compute
|
||||
cluster which has no connection to the internet. During model
|
||||
initialization, stable-diffusion tries to download the Bert tokenizer
|
||||
and a file needed by the kornia library. This obviously didn't work
|
||||
for me.
|
||||
|
||||
To work around this, I have modified ldm/modules/encoders/modules.py
|
||||
to look for locally cached Bert files rather than attempting to
|
||||
download them. For this to work, you must run
|
||||
"scripts/preload_models.py" once from an internet-connected machine
|
||||
prior to running the code on an isolated one. This assumes that both
|
||||
machines share a common network-mounted filesystem with a common
|
||||
.cache directory.
|
||||
|
||||
```

||||

# Troubleshooting
|
||||
|
||||
Here are a few common installation problems and their solutions. Often
|
||||
these are caused by incomplete installations or crashes during the
|
||||
install process.
|
||||
|
||||
- PROBLEM: During "conda env create -f environment.yaml", conda
|
||||
hangs indefinitely.
|
||||
|
||||
- SOLUTION: Enter the stable-diffusion directory and completely
|
||||
remove the "src" directory and all its contents. The safest way
|
||||
to do this is to enter the stable-diffusion directory and
|
||||
give the command "git clean -f". If this still doesn't fix
|
||||
the problem, try "conda clean -all" and then restart at the
|
||||
"conda env create" step.
|
||||
|
||||
---
|
||||
|
||||
- PROBLEM: dream.py crashes with the complaint that it can't find
|
||||
ldm.simplet2i.py. Or it complains that function is being passed
|
||||
incorrect parameters.
|
||||
|
||||
- SOLUTION: Reinstall the stable diffusion modules. Enter the
|
||||
stable-diffusion directory and give the command "pip install -e ."
|
||||
|
||||
---
|
||||
|
||||
- PROBLEM: dream.py dies, complaining of various missing modules, none
|
||||
of which starts with "ldm".
|
||||
|
||||
- SOLUTION: From within the stable-diffusion directory, run "conda env
|
||||
update -f environment.yaml" This is also frequently the solution to
|
||||
complaints about an unknown function in a module.
|
||||
|
||||
---
|
||||
|
||||
- PROBLEM: There's a feature or bugfix in the Stable Diffusion GitHub
|
||||
that you want to try out.
|
||||
|
||||
- SOLUTION: If the fix/feature is on the "main" branch, enter the stable-diffusion
|
||||
directory and do a "git pull". Usually this will be sufficient, but if
|
||||
you start to see errors about missing or incorrect modules, use the
|
||||
command "pip install -e ." and/or "conda env update -f environment.yaml"
|
||||
(These commands won't break anything.)
|
||||
|
||||
- If the feature/fix is on a branch (e.g. "foo-bugfix"), the recipe is similar, but
|
||||
do a "git pull <name of branch>".
|
||||
|
||||
- If the feature/fix is in a pull request that has not yet been made
|
||||
part of the main branch or a feature/bugfix branch, then from the page
|
||||
for the desired pull request, look for the line at the top that reads
|
||||
"xxxx wants to merge xx commits into lstein:main from YYYYYY". Copy
|
||||
the URL in YYYY. It should have the format
|
||||
https://github.com/<name of contributor>/stable-diffusion/tree/<name
|
||||
of branch>
|
||||
|
||||
- Then **go to the directory above stable-diffusion**, and rename the
|
||||
directory to "stable-diffusion.lstein", "stable-diffusion.old", or
|
||||
whatever. You can then git clone the branch that contains the
|
||||
pull request:
|
||||
|
||||
```
|
||||
git clone https://github.com/<name of contributor>/stable-diffusion/tree/<name
|
||||
of branch>
|
||||
```
|
||||
|
||||
You will need to go through the install procedure again, but it should
|
||||
be fast because all the dependencies are already loaded.
|
||||

### Text-to-Image with Stable Diffusion
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||

Stable Diffusion is a latent diffusion model conditioned on the (non-pooled) text embeddings of a CLIP ViT-L/14 text encoder.

||||

|

Note: The inference config for all v1 versions is designed to be used with EMA-only checkpoints.
|
||||
For this reason `use_ema=False` is set in the configuration, otherwise the code will try to switch from
|
||||
non-EMA to EMA weights. If you want to examine the effect of EMA vs no EMA, we provide "full" checkpoints
|
||||
which contain both types of weights. For these, `use_ema=False` will load and use the non-EMA weights.

|
||||
Here, strength is a value between 0.0 and 1.0, that controls the amount of noise that is added to the input image.
|
||||
Values that approach 1.0 allow for lots of variations but will also produce images that are not semantically consistent with the input. See the following example.

This procedure can, for example, also be used to upscale samples from the base model.

# **Interactive Command-Line Interface**
|
||||
|
||||
The `dream.py` script, located in `scripts/dream.py`, provides an interactive interface to image generation similar to the "dream mothership" bot that Stable AI provided on its Discord server.
|
||||
|
||||
Unlike the txt2img.py and img2img.py scripts provided in the original CompViz/stable-diffusion source code repository, the time-consuming initialization of the AI model initialization only happens once. After that image generation
|
||||
from the command-line interface is very fast.
|
||||
|
||||
The script uses the readline library to allow for in-line editing, command history (up and down arrows), autocompletion, and more. To help keep track of which prompts generated which images, the script writes a log file of image names and prompts to the selected output directory.
|
||||
|
||||
In addition, as of version 1.02, it also writes the prompt into the PNG file's metadata where it can be retrieved using scripts/images2prompt.py
|
||||
|
||||
The script is confirmed to work on Linux, Windows and Mac systems.
|
||||
|
||||
_Note:_ This script runs from the command-line or can be used as a Web application. The Web GUI is currently rudimentary, but a much better replacement is on its way.
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/dream.py

||||
* Initializing, be patient...

||||

|

|
||||
The `dream>` prompt's arguments are pretty much identical to those
|
||||
used in the Discord bot, except you don't need to type "!dream" (it
|
||||
doesn't hurt if you do). A significant change is that creation of
|
||||
individual images is now the default unless --grid (-g) is given. A
|
||||
full list is given in [List of prompt arguments]
|
||||
(#list-of-prompt-arguments).
|
||||
|
||||
# Arguments
|
||||
|
||||
The script itself also recognizes a series of command-line switches
|
||||
that will change important global defaults, such as the directory for
|
||||
image outputs and the location of the model weight files.
|
||||
|
||||
## List of arguments recognized at the command line:
|
||||
|
||||
These command-line arguments can be passed to dream.py when you first
|
||||
run it from the Windows, Mac or Linux command line. Some set defaults
|
||||
that can be overridden on a per-prompt basis (see [List of prompt
|
||||
arguments] (#list-of-prompt-arguments). Others
|
||||
|
||||
| Argument | Shortcut | Default | Description |
|
||||
|--------------------|------------|---------------------|--------------|
|
||||
| --help | -h | | Print a concise help message. |
|
||||
| --outdir <path> | -o<path> | outputs/img_samples | Location for generated images. |
|
||||
| --prompt_as_dir | -p | False | Name output directories using the prompt text. |
|
||||
| --from_file <path> | | None | Read list of prompts from a file. Use "-" to read from standard input |
|
||||
| --model <modelname>| | stable-diffusion-1.4| Loads model specified in configs/models.yaml. Currently one of "stable-diffusion-1.4" or "laion400m"|
|
||||
| --full_precision | -F | False | Run in slower full-precision mode. Needed for Macintosh M1/M2 hardware and some older video cards. |
|
||||
| --web | | False | Start in web server mode |
|
||||
| --host <ip addr> | | localhost | Which network interface web server should listen on. Set to 0.0.0.0 to listen on any. |
|
||||
| --port <port> | | 9090 | Which port web server should listen for requests on. |
|
||||
| --config <path> | | configs/models.yaml | Configuration file for models and their weights. |
|
||||
| --iterations <int> | -n<int> | 1 | How many images to generate per prompt. |
|
||||
| --grid | -g | False | Save all image series as a grid rather than individually. |
|
||||
| --sampler <sampler>| -A<sampler>| k_lms | Sampler to use. Use -h to get list of available samplers. |
|
||||
| --seamless | | False | Create interesting effects by tiling elements of the image. |
|
||||

|
||||
| --device <device> | -d<device>| torch.cuda.current_device() | Device to run SD on, e.g. "cuda:0" |
|
||||
|
||||
These arguments are deprecated but still work:
|
||||
|
||||
| Argument | Shortcut | Default | Description |
|
||||
|--------------------|------------|---------------------|--------------|
|
||||
| --weights <path> | | None | Pth to weights file; use `--model stable-diffusion-1.4` instead |
|
||||
| --laion400m | -l | False | Use older LAION400m weights; use `--model=laion400m` instead |
|
||||
|
||||
**A note on path names:** On Windows systems, you may run into
|
||||
problems when passing the dream script standard backslashed path
|
||||
names because the Python interpreter treats "\" as an escape.
|
||||
You can either double your slashes (ick): C:\\\\path\\\\to\\\\my\\\\file, or
|
||||
use Linux/Mac style forward slashes (better): C:/path/to/my/file.
|
||||
|
||||
## List of prompt arguments
|
||||
|
||||
After the dream.py script initializes, it will present you with a
|
||||
**dream>** prompt. Here you can enter information to generate images
|
||||
from text (txt2img), to embellish an existing image or sketch
|
||||
(img2img), or to selectively alter chosen regions of the image
|
||||
(inpainting).
|
||||
|
||||
### This is an example of txt2img:
|
||||
|
||||
~~~~
|
||||
dream> waterfall and rainbow -W640 -H480
|
||||
~~~~
|
||||
|
||||
This will create the requested image with the dimensions 640 (width)
|
||||
and 480 (height).
|
||||
|
||||
Here are the dream> command that apply to txt2img:
|
||||
|
||||
| Argument | Shortcut | Default | Description |
|
||||
|--------------------|------------|---------------------|--------------|
|
||||
| "my prompt" | | | Text prompt to use. The quotation marks are optional. |
|
||||
| --width <int> | -W<int> | 512 | Width of generated image |
|
||||
| --height <int> | -H<int> | 512 | Height of generated image |
|
||||
| --iterations <int> | -n<int> | 1 | How many images to generate from this prompt |
|
||||
| --steps <int> | -s<int> | 50 | How many steps of refinement to apply |
|
||||
| --cfg_scale <float>| -C<float> | 7.5 | How hard to try to match the prompt to the generated image; any number greater than 0.0 works, but the useful range is roughly 5.0 to 20.0 |
|
||||
| --seed <int> | -S<int> | None | Set the random seed for the next series of images. This can be used to recreate an image generated previously.|
|
||||
| --sampler <sampler>| -A<sampler>| k_lms | Sampler to use. Use -h to get list of available samplers. |
|
||||
| --grid | -g | False | Turn on grid mode to return a single image combining all the images generated by this prompt |
|
||||
| --individual | -i | True | Turn off grid mode (deprecated; leave off --grid instead) |
|
||||
| --outdir <path> | -o<path> | outputs/img_samples | Temporarily change the location of these images |
|
||||
| --seamless | | False | Activate seamless tiling for interesting effects |
|
||||
| --log_tokenization | -t | False | Display a color-coded list of the parsed tokens derived from the prompt |
|
||||
| --skip_normalization| -x | False | Weighted subprompts will not be normalized. See [Weighted Prompts](./OTHER.md#weighted-prompts) |
|
||||
| --upscale <int> <float> | -U <int> <float> | -U 1 0.75| Upscale image by magnification factor (2, 4), and set strength of upscaling (0.0-1.0). If strength not set, will default to 0.75. |
|
||||
| --gfpgan_strength <float> | -G <float> | -G0 | Fix faces using the GFPGAN algorithm; argument indicates how hard the algorithm should try (0.0-1.0) |
|
||||
| --save_original | -save_orig| False | When upscaling or fixing faces, this will cause the original image to be saved rather than replaced. |
|
||||
| --variation <float> |-v<float>| 0.0 | Add a bit of noise (0.0=none, 1.0=high) to the image in order to generate a series of variations. Usually used in combination with -S<seed> and -n<int> to generate a series a riffs on a starting image. See [Variations](./VARIATIONS.md). |
|
||||
| --with_variations <pattern> | -V<pattern>| None | Combine two or more variations. See [Variations](./VARIATIONS.md) for now to use this. |
|
||||
|
||||
Note that the width and height of the image must be multiples of
|
||||
64. You can provide different values, but they will be rounded down to
|
||||
the nearest multiple of 64.
|
||||
|
||||
|
||||
### This is an example of img2img:
|
||||
|
||||
~~~~
|
||||
dream> waterfall and rainbow -I./vacation-photo.png -W640 -H480 --fit
|
||||
~~~~
|
||||
|
||||
This will modify the indicated vacation photograph by making it more
|
||||
like the prompt. Results will vary greatly depending on what is in the
|
||||
image. We also ask to --fit the image into a box no bigger than
|
||||
640x480. Otherwise the image size will be identical to the provided
|
||||
photo and you may run out of memory if it is large.
|
||||
|
||||
In addition to the command-line options recognized by txt2img, img2img
|
||||
accepts additional options:
|
||||
|
||||
| Argument | Shortcut | Default | Description |
|
||||
|--------------------|------------|---------------------|--------------|
|
||||
| --init_img <path> | -I<path> | None | Path to the initialization image |
|
||||
| --fit | -F | False | Scale the image to fit into the specified -H and -W dimensions |
|
||||
| --strength <float> | -s<float> | 0.75 | How hard to try to match the prompt to the initial image. Ranges from 0.0-0.99, with higher values replacing the initial image completely.|
|
||||
|
||||
### This is an example of inpainting:
|
||||
|
||||
~~~~
|
||||
dream> waterfall and rainbow -I./vacation-photo.png -M./vacation-mask.png -W640 -H480 --fit
|
||||
~~~~
|
||||
|
||||
This will do the same thing as img2img, but image alterations will
|
||||
only occur within transparent areas defined by the mask file specified
|
||||
by -M. You may also supply just a single initial image with the areas
|
||||
to overpaint made transparent, but you must be careful not to destroy
|
||||
the pixels underneath when you create the transparent areas. See
|
||||
[Inpainting](./INPAINTING.md) for details.
|
||||
|
||||
inpainting accepts all the arguments used for txt2img and img2img, as
|
||||
well as the --mask (-M) argument:
|
||||
|
||||
| Argument | Shortcut | Default | Description |
|
||||
|--------------------|------------|---------------------|--------------|
|
||||
| --init_mask <path> | -M<path> | None |Path to an image the same size as the initial_image, with areas for inpainting made transparent.|
|
||||
|
||||
|
||||
# Command-line editing and completion
|
||||
|
||||
If you are on a Macintosh or Linux machine, the command-line offers
|
||||
convenient history tracking, editing, and command completion.
|
||||
|
||||
- To scroll through previous commands and potentially edit/reuse them, use the up and down cursor keys.
|
||||
- To edit the current command, use the left and right cursor keys to position the cursor, and then backspace, delete or insert characters.
|
||||
- To move to the very beginning of the command, type CTRL-A (or command-A on the Mac)
|
||||
- To move to the end of the command, type CTRL-E.
|
||||
- To cut a section of the command, position the cursor where you want to start cutting and type CTRL-K.
|
||||
- To paste a cut section back in, position the cursor where you want to paste, and type CTRL-Y
|
||||
|
||||
Windows users can get similar, but more limited, functionality if they
|
||||
launch dream.py with the "winpty" program:
|
||||
|
||||
~~~
|
||||
> winpty python scripts\dream.py
|
||||
~~~
|
||||
|
||||
On the Mac and Linux platforms, when you exit dream.py, the last 1000
|
||||
lines of your command-line history will be saved. When you restart
|
||||
dream.py, you can access the saved history using the up-arrow key.
|
||||
|
||||
In addition, limited command-line completion is installed. In various
|
||||
contexts, you can start typing your command and press tab. A list of
|
||||
potential completions will be presented to you. You can then type a
|
||||
little more, hit tab again, and eventually autocomplete what you want.
|
||||
|
||||
When specifying file paths using the one-letter shortcuts, the CLI
|
||||
will attempt to complete pathnames for you. This is most handy for the
|
||||
-I (init image) and -M (init mask) paths. To initiate completion, start
|
||||
the path with a slash ("/") or "./". For example:
|
||||
|
||||
~~~
|
||||
dream> zebra with a mustache -I./test-pictures<TAB>
|
||||
-I./test-pictures/Lincoln-and-Parrot.png -I./test-pictures/zebra.jpg -I./test-pictures/madonna.png
|
||||
-I./test-pictures/bad-sketch.png -I./test-pictures/man_with_eagle/
|
||||
~~~
|
||||
|
||||
You can then type "z", hit tab again, and it will autofill to "zebra.jpg".
|
||||
|
||||
More text completion features (such as autocompleting seeds) are on their way.

# **Image-to-Image**
|
||||
|
||||
This script also provides an img2img feature that lets you seed your
|
||||
creations with an initial drawing or photo. This is a really cool
|
||||
feature that tells stable diffusion to build the prompt on top of the
|
||||
image you provide, preserving the original's basic shape and
|
||||
layout. To use it, provide the `--init_img` option as shown here:
|
||||
|
||||
```
|
||||
dream> "waterfall and rainbow" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
|
||||
```
|
||||
|
||||
The `--init_img (-I)` option gives the path to the seed
|
||||
picture. `--strength (-f)` controls how much the original will be
|
||||
modified, ranging from `0.0` (keep the original intact), to `1.0`
|
||||
(ignore the original completely). The default is `0.75`, and ranges
|
||||
from `0.25-0.75` give interesting results.
|
||||
|
||||
You may also pass a `-v<count>` option to generate count variants on
|
||||
the original image. This is done by passing the first generated image
|
||||
back into img2img the requested number of times. It generates
|
||||
interesting variants.
|
||||
|
||||
If the initial image contains transparent regions, then Stable
|
||||
Diffusion will only draw within the transparent regions, a process
|
||||
called "inpainting". However, for this to work correctly, the color
|
||||
information underneath the transparent needs to be preserved, not
|
||||
erased. See [Creating Transparent Images For
|
||||
Inpainting](./INPAINTING.md#creating-transparent-regions-for-inpainting)
|
||||
for details.

# **Creating Transparent Regions for Inpainting**
|
||||
|
||||
Inpainting is really cool. To do it, you start with an initial image
|
||||
and use a photoeditor to make one or more regions transparent
|
||||
(i.e. they have a "hole" in them). You then provide the path to this
|
||||
image at the dream> command line using the `-I` switch. Stable
|
||||
Diffusion will only paint within the transparent region.
|
||||
|
||||
There's a catch. In the current implementation, you have to prepare
|
||||
the initial image correctly so that the underlying colors are
|
||||
preserved under the transparent area. Many imaging editing
|
||||
applications will by default erase the color information under the
|
||||
transparent pixels and replace them with white or black, which will
|
||||
lead to suboptimal inpainting. You also must take care to export the
|
||||
PNG file in such a way that the color information is preserved.
|
||||
|
||||
If your photoeditor is erasing the underlying color information,
|
||||
`dream.py` will give you a big fat warning. If you can't find a way to
|
||||
coax your photoeditor to retain color values under transparent areas,
|
||||
then you can combine the `-I` and `-M` switches to provide both the
|
||||
original unedited image and the masked (partially transparent) image:
|
||||
|
||||
```
|
||||
dream> man with cat on shoulder -I./images/man.png -M./images/man-transparent.png
|
||||
```
|
||||
|
||||
We are hoping to get rid of the need for this workaround in an upcoming release.
|
||||
|
||||
## Recipe for GIMP
|
||||
|
||||
[GIMP](https://www.gimp.org/) is a popular Linux photoediting tool.
|
||||
|
||||
1. Open image in GIMP.
|
||||
2. Layer->Transparency->Add Alpha Channel
|
||||
3. Use lasoo tool to select region to mask
|
||||
4. Choose Select -> Float to create a floating selection
|
||||
5. Open the Layers toolbar (^L) and select "Floating Selection"
|
||||
6. Set opacity to 0%
|
||||
7. Export as PNG
|
||||
8. In the export dialogue, Make sure the "Save colour values from
|
||||
transparent pixels" checkbox is selected.

## **Reading Prompts from a File**
|
||||
|
||||
You can automate `dream.py` by providing a text file with the prompts
|
||||
you want to run, one line per prompt. The text file must be composed
|
||||
with a text editor (e.g. Notepad) and not a word processor. Each line
|
||||
should look like what you would type at the dream> prompt:
|
||||
|
||||
```
|
||||
a beautiful sunny day in the park, children playing -n4 -C10
|
||||
stormy weather on a mountain top, goats grazing -s100
|
||||
innovative packaging for a squid's dinner -S137038382
|
||||
```
|
||||
|
||||
Then pass this file's name to `dream.py` when you invoke it:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py --from_file "path/to/prompts.txt"
|
||||
```
|
||||
|
||||
You may read a series of prompts from standard input by providing a filename of `-`:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ echo "a beautiful day" | python3 scripts/dream.py --from_file -
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## **Shortcuts: Reusing Seeds**
|
||||
|
||||
Since it is so common to reuse seeds while refining a prompt, there is now a shortcut as of version 1.11. Provide a `**-S**` (or `**--seed**`)
|
||||
switch of `-1` to use the seed of the most recent image generated. If you produced multiple images with the `**-n**` switch, then you can go back further using -2, -3, etc. up to the first image generated by the previous command. Sorry, but you can't go back further than one command.
|
||||
|
||||
Here's an example of using this to do a quick refinement. It also illustrates using the new `**-G**` switch to turn on upscaling and face enhancement (see previous section):
|
||||
|
||||
```
|
||||
dream> a cute child playing hopscotch -G0.5
|
||||
[...]
|
||||
outputs/img-samples/000039.3498014304.png: "a cute child playing hopscotch" -s50 -W512 -H512 -C7.5 -mk_lms -S3498014304
|
||||
|
||||
# I wonder what it will look like if I bump up the steps and set facial enhancement to full strength?
|
||||
dream> a cute child playing hopscotch -G1.0 -s100 -S -1
|
||||
reusing previous seed 3498014304
|
||||
[...]
|
||||
outputs/img-samples/000040.3498014304.png: "a cute child playing hopscotch" -G1.0 -s100 -W512 -H512 -C7.5 -mk_lms -S3498014304
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## **Weighted Prompts**
|
||||
|
||||
You may weight different sections of the prompt to tell the sampler to attach different levels of
|
||||
priority to them, by adding `:(number)` to the end of the section you wish to up- or downweight.
|
||||
For example consider this prompt:
|
||||
|
||||
```
|
||||
tabby cat:0.25 white duck:0.75 hybrid
|
||||
```
|
||||
|
||||
This will tell the sampler to invest 25% of its effort on the tabby
|
||||
cat aspect of the image and 75% on the white duck aspect
|
||||
(surprisingly, this example actually works). The prompt weights can
|
||||
use any combination of integers and floating point numbers, and they
|
||||
do not need to add up to 1.
|
||||

||||

|
||||
|
||||
## **Simplified API**
|
||||
|
||||
For programmers who wish to incorporate stable-diffusion into other products, this repository includes a simplified API for text to image generation, which lets you create images from a prompt in just three lines of code:
|
||||
|
||||
```
|
||||
from ldm.generate import Generate
|
||||
g = Generate()
|
||||
outputs = g.txt2img("a unicorn in manhattan")
|
||||
```
|
||||
|
||||
Outputs is a list of lists in the format [filename1,seed1],[filename2,seed2]...].
|
||||
|
||||
Please see ldm/generate.py for more information. A set of example scripts is coming RSN.
|
||||

|
||||
|
||||
## **Preload Models**
|
||||
|
||||
In situations where you have limited internet connectivity or are
|
||||
blocked behind a firewall, you can use the preload script to preload
|
||||
the required files for Stable Diffusion to run.
|
||||
|
||||
The preload script `scripts/preload_models.py` needs to be run once at
|
||||
least while connected to the internet. In the following runs, it will
|
||||
load up the cached versions of the required files from the `.cache`
|
||||
directory of the system.
|
||||

# **Personalizing Text-to-Image Generation**
|
||||
|
||||
You may personalize the generated images to provide your own styles or objects by training a new LDM checkpoint and introducing a new vocabulary to the fixed model as a (.pt) embeddings file. Alternatively, you may use or train HuggingFace Concepts embeddings files (.bin) from https://huggingface.co/sd-concepts-library and its associated notebooks.
|
||||
|
||||
**Training**
|
||||
|
||||
To train, prepare a folder that contains images sized at 512x512 and execute the following:
|
||||
|
||||
**WINDOWS**: As the default backend is not available on Windows, if you're using that platform, set the environment variable `PL_TORCH_DISTRIBUTED_BACKEND=gloo`
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./main.py --base ./configs/stable-diffusion/v1-finetune.yaml \
|
||||
-t \
|
||||
--actual_resume ./models/ldm/stable-diffusion-v1/model.ckpt \
|
||||
-n my_cat \
|
||||
--gpus 0, \
|
||||
--data_root D:/textual-inversion/my_cat \
|
||||
--init_word 'cat'
|
||||
```
|
||||
|
||||
During the training process, files will be created in
|
||||
/logs/[project][time][project]/ where you can see the process.
|
||||
|
||||
Conditioning contains the training prompts inputs, reconstruction the
|
||||
input images for the training epoch samples, samples scaled for a
|
||||
sample of the prompt and one with the init word provided.
|
||||
|
||||
On a RTX3090, the process for SD will take ~1h @1.6 iterations/sec.
|
||||
|
||||
_Note_: According to the associated paper, the optimal number of
|
||||
images is 3-5. Your model may not converge if you use more images than
|
||||
that.
|
||||
|
||||
Training will run indefinitely, but you may wish to stop it (with
|
||||
ctrl-c) before the heat death of the universe, when you find a low
|
||||
loss epoch or around ~5000 iterations. Note that you can set a fixed
|
||||
limit on the number of training steps by decreasing the "max_steps"
|
||||
option in configs/stable_diffusion/v1-finetune.yaml (currently set to
|
||||
4000000)
|
||||
|
||||
**Running**
|
||||
|
||||
Once the model is trained, specify the trained .pt or .bin file when
|
||||
starting dream using
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/dream.py --embedding_path /path/to/embedding.pt --full_precision
|
||||
```
|
||||
|
||||
Then, to utilize your subject at the dream prompt
|
||||
|
||||
```
|
||||
dream> "a photo of *"
|
||||
```
|
||||
|
||||
This also works with image2image
|
||||
|
||||
```
|
||||
dream> "waterfall and rainbow in the style of *" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
|
||||
```
|
||||
|
||||
For .pt files it's also possible to train multiple tokens (modify the placeholder string in `configs/stable-diffusion/v1-finetune.yaml`) and combine LDM checkpoints using:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 ./scripts/merge_embeddings.py \
|
||||
--manager_ckpts /path/to/first/embedding.pt /path/to/second/embedding.pt [...] \
|
||||
--output_path /path/to/output/embedding.pt
|
||||
```

# **GFPGAN and Real-ESRGAN Support**
|
||||
|
||||
The script also provides the ability to do face restoration and
|
||||
upscaling with the help of GFPGAN and Real-ESRGAN respectively.
|
||||
|
||||
As of version 1.14, environment.yaml will install the Real-ESRGAN package into the
|
||||
standard install location for python packages, and will put GFPGAN into a subdirectory of "src"
|
||||
in the stable-diffusion directory.
|
||||
(The reason for this is that the standard GFPGAN distribution has a minor bug that adversely affects image
|
||||
color.) Upscaling with Real-ESRGAN should "just work" without further intervention. Simply pass the --upscale (-U)
|
||||
option on the dream> command line, or indicate the desired scale on the popup in the Web GUI.
|
||||
|
||||
For **GFPGAN** to work, there is one additional step needed. You will need to download and
|
||||
copy the GFPGAN [models file](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth)
|
||||
into **src/gfpgan/experiments/pretrained_models**. On Mac and Linux systems, here's how you'd do it using
|
||||
**wget**:
|
||||
~~~~
|
||||
> wget https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth src/gfpgan/experiments/pretrained_models/
|
||||
~~~~
|
||||
|
||||
Make sure that you're in the stable-diffusion directory when you do this.
|
||||
|
||||
Alternatively, if you have GFPGAN installed elsewhere, or if you are using
|
||||
an earlier version of this package which asked you to install GFPGAN in a
|
||||
sibling directory, you may use the `--gfpgan_dir` argument with `dream.py` to set a
|
||||
custom path to your GFPGAN directory. _There are other GFPGAN related
|
||||
boot arguments if you wish to customize further._
|
||||
|
||||
**Note: Internet connection needed:**
|
||||
Users whose GPU machines are isolated from the Internet (e.g. on a
|
||||
University cluster) should be aware that the first time you run
|
||||
dream.py with GFPGAN and Real-ESRGAN turned on, it will try to
|
||||
download model files from the Internet. To rectify this, you may run
|
||||
`python3 scripts/preload_models.py` after you have installed GFPGAN
|
||||
and all its dependencies.
|
||||
|
||||
**Usage**
|
||||
|
||||
You will now have access to two new prompt arguments.
|
||||
|
||||
**Upscaling**
|
||||
|
||||
`-U : <upscaling_factor> <upscaling_strength>`
|
||||
|
||||
The upscaling prompt argument takes two values. The first value is a
|
||||
scaling factor and should be set to either `2` or `4` only. This will
|
||||
either scale the image 2x or 4x respectively using different models.
|
||||
|
||||
You can set the scaling stength between `0` and `1.0` to control
|
||||
intensity of the of the scaling. This is handy because AI upscalers
|
||||
generally tend to smooth out texture details. If you wish to retain
|
||||
some of those for natural looking results, we recommend using values
|
||||
between `0.5 to 0.8`.
|
||||
|
||||
If you do not explicitly specify an upscaling_strength, it will
|
||||
default to 0.75.
|
||||
|
||||
**Face Restoration**
|
||||
|
||||
`-G : <gfpgan_strength>`
|
||||
|
||||
This prompt argument controls the strength of the face restoration
|
||||
that is being applied. Similar to upscaling, values between `0.5 to 0.8` are recommended.
|
||||
|
||||
You can use either one or both without any conflicts. In cases where
|
||||
you use both, the image will be first upscaled and then the face
|
||||
restoration process will be executed to ensure you get the highest
|
||||
quality facial features.
|
||||
|
||||
`--save_orig`
|
||||
|
||||
When you use either `-U` or `-G`, the final result you get is upscaled
|
||||
or face modified. If you want to save the original Stable Diffusion
|
||||
generation, you can use the `-save_orig` prompt argument to save the
|
||||
original unaffected version too.
|
||||
|
||||
**Example Usage**
|
||||
|
||||
```
|
||||
dream > superman dancing with a panda bear -U 2 0.6 -G 0.4
|
||||
```
|
||||
|
||||
This also works with img2img:
|
||||
|
||||
```
|
||||
dream> a man wearing a pineapple hat -I path/to/your/file.png -U 2 0.5 -G 0.6
|
||||
```
|
||||
|
||||
**Note**
|
||||
|
||||
GFPGAN and Real-ESRGAN are both memory intensive. In order to avoid
|
||||
crashes and memory overloads during the Stable Diffusion process,
|
||||
these effects are applied after Stable Diffusion has completed its
|
||||
work.
|
||||
|
||||
In single image generations, you will see the output right away but
|
||||
when you are using multiple iterations, the images will first be
|
||||
generated and then upscaled and face restored after that process is
|
||||
complete. While the image generation is taking place, you will still
|
||||
be able to preview the base images.
|
||||
|
||||
If you wish to stop during the image generation but want to upscale or
|
||||
face restore a particular generated image, pass it again with the same
|
||||
prompt and generated seed along with the `-U` and `-G` prompt
|
||||
arguments to perform those actions.

# Barebones Web Server
|
||||
|
||||
As of version 1.10, this distribution comes with a bare bones web server (see screenshot). To use it, run the `dream.py` script by adding the `**--web**` option.
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py --web
|
||||
```
|
||||
|
||||
You can then connect to the server by pointing your web browser at http://localhost:9090, or to the network name or IP address of the server.
|
||||
|
||||
Kudos to [Tesseract Cat](https://github.com/TesseractCat) for contributing this code, and to [dagf2101](https://github.com/dagf2101) for refining it.

# **Frequently Asked Questions**
|
||||
|
||||
Here are a few common installation problems and their solutions. Often these are caused by incomplete installations or crashes during the
|
||||
install process.
|
||||
|
||||
---
|
||||
|
||||
**QUESTION**
|
||||
|
||||
During `conda env create -f environment.yaml`, conda hangs indefinitely.
|
||||
|
||||
**SOLUTION**
|
||||
|
||||
Enter the stable-diffusion directory and completely remove the `src` directory and all its contents. The safest way to do this is to enter the stable-diffusion directory and give the command `git clean -f`. If this still doesn't fix the problem, try "conda clean -all" and then restart at the `conda env create` step.
|
||||
|
||||
---
|
||||
|
||||
**QUESTION**
|
||||
|
||||
`dream.py` crashes with the complaint that it can't find `ldm.simplet2i.py`. Or it complains that function is being passed incorrect parameters.
|
||||
|
||||
**SOLUTION**
|
||||
|
||||
Reinstall the stable diffusion modules. Enter the `stable-diffusion` directory and give the command `pip install -e .`
|
||||
|
||||
---
|
||||
|
||||
**QUESTION**
|
||||
|
||||
`dream.py` dies, complaining of various missing modules, none of which starts with `ldm``.
|
||||
|
||||
**SOLUTION**
|
||||
|
||||
From within the `stable-diffusion` directory, run `conda env update -f environment.yaml` This is also frequently the solution to
|
||||
complaints about an unknown function in a module.
|
||||
|
||||
---
|
||||
|
||||
**QUESTION**
|
||||
|
||||
There's a feature or bugfix in the Stable Diffusion GitHub that you want to try out.
|
||||
|
||||
**SOLUTION**
|
||||
|
||||
**Main Branch**
|
||||
|
||||
If the fix/feature is on the `main` branch, enter the stable-diffusion directory and do a `git pull`.
|
||||
|
||||
Usually this will be sufficient, but if you start to see errors about missing or incorrect modules, use the command `pip install -e .` and/or `conda env update -f environment.yaml` (These commands won't break anything.)
|
||||
|
||||
**Sub Branch**
|
||||
|
||||
If the feature/fix is on a branch (e.g. "_foo-bugfix_"), the recipe is similar, but do a `git pull <name of branch>`.
|
||||
|
||||
**Not Committed**
|
||||
|
||||
If the feature/fix is in a pull request that has not yet been made part of the main branch or a feature/bugfix branch, then from the page for the desired pull request, look for the line at the top that reads "_xxxx wants to merge xx commits into lstein:main from YYYYYY_". Copy the URL in YYYY. It should have the format `https://github.com/<name of contributor>/stable-diffusion/tree/<name of branch>`
|
||||
|
||||
Then **go to the directory above stable-diffusion** and rename the directory to "_stable-diffusion.lstein_", "_stable-diffusion.old_", or anything else. You can then git clone the branch that contains the pull request:
|
||||
|
||||
```
|
||||
git clone https://github.com/<name of contributor>/stable-diffusion/tree/<name
|
||||
of branch>
|
||||
```
|
||||
|
||||
You will need to go through the install procedure again, but it should be fast because all the dependencies are already loaded.

# **Linux Installation**
|
||||
|
||||
1. You will need to install the following prerequisites if they are not already available. Use your operating system's preferred installer
|
||||
|
||||
- Python (version 3.8.5 recommended; higher may work)
|
||||
- git
|
||||
|
||||
2. Install the Python Anaconda environment manager.
|
||||
|
||||
```
|
||||
~$ wget https://repo.anaconda.com/archive/Anaconda3-2022.05-Linux-x86_64.sh
|
||||
~$ chmod +x Anaconda3-2022.05-Linux-x86_64.sh
|
||||
~$ ./Anaconda3-2022.05-Linux-x86_64.sh
|
||||
```
|
||||
|
||||
After installing anaconda, you should log out of your system and log back in. If the installation
|
||||
worked, your command prompt will be prefixed by the name of the current anaconda environment - `(base)`.
|
||||
|
||||
3. Copy the stable-diffusion source code from GitHub:
|
||||
|
||||
```
|
||||
(base) ~$ git clone https://github.com/lstein/stable-diffusion.git
|
||||
```
|
||||
|
||||
This will create stable-diffusion folder where you will follow the rest of the steps.
|
||||
|
||||
4. Enter the newly-created stable-diffusion folder. From this step forward make sure that you are working in the stable-diffusion directory!
|
||||
|
||||
```
|
||||
(base) ~$ cd stable-diffusion
|
||||
(base) ~/stable-diffusion$
|
||||
```
|
||||
|
||||
5. Use anaconda to copy necessary python packages, create a new python environment named `ldm` and activate the environment.
|
||||
|
||||
```
|
||||
(base) ~/stable-diffusion$ conda env create -f environment.yaml
|
||||
(base) ~/stable-diffusion$ conda activate ldm
|
||||
(ldm) ~/stable-diffusion$
|
||||
```
|
||||
|
||||
After these steps, your command prompt will be prefixed by `(ldm)` as shown above.
|
||||
|
||||
6. Load a couple of small machine-learning models required by stable diffusion:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/preload_models.py
|
||||
```
|
||||
|
||||
Note that this step is necessary because I modified the original just-in-time model loading scheme to allow the script to work on GPU machines that are not internet connected. See [Preload Models](../features/OTHER.md#preload-models)
|
||||
|
||||
7. Now you need to install the weights for the stable diffusion model.
|
||||
|
||||
- For running with the released weights, you will first need to set up an acount with Hugging Face (https://huggingface.co).
|
||||
- Use your credentials to log in, and then point your browser at https://huggingface.co/CompVis/stable-diffusion-v-1-4-original.
|
||||
- You may be asked to sign a license agreement at this point.
|
||||
- Click on "Files and versions" near the top of the page, and then click on the file named "sd-v1-4.ckpt". You'll be taken to a page that prompts you to click the "download" link. Save the file somewhere safe on your local machine.
|
||||
|
||||
Now run the following commands from within the stable-diffusion directory. This will create a symbolic link from the stable-diffusion model.ckpt file, to the true location of the sd-v1-4.ckpt file.
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ mkdir -p models/ldm/stable-diffusion-v1
|
||||
(ldm) ~/stable-diffusion$ ln -sf /path/to/sd-v1-4.ckpt models/ldm/stable-diffusion-v1/model.ckpt
|
||||
```
|
||||
|
||||
8. Start generating images!
|
||||
|
||||
```
|
||||
# for the pre-release weights use the -l or --liaon400m switch
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py -l
|
||||
|
||||
# for the post-release weights do not use the switch
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py
|
||||
|
||||
# for additional configuration switches and arguments, use -h or --help
|
||||
(ldm) ~/stable-diffusion$ python3 scripts/dream.py -h
|
||||
```
|
||||
|
||||
9. Subsequently, to relaunch the script, be sure to run "conda activate ldm" (step 5, second command), enter the `stable-diffusion` directory, and then launch the dream script (step 8). If you forget to activate the ldm environment, the script will fail with multiple `ModuleNotFound` errors.
|
||||
|
||||
### Updating to newer versions of the script
|
||||
|
||||
This distribution is changing rapidly. If you used the `git clone` method (step 5) to download the stable-diffusion directory, then to update to the latest and greatest version, launch the Anaconda window, enter `stable-diffusion` and type:
|
||||
|
||||
```
|
||||
(ldm) ~/stable-diffusion$ git pull
|
||||
```
|
||||
|
||||
This will bring your local copy into sync with the remote one.

|
||||
with cell-by-cell installation steps. It will download the code in
|
||||
this repo as one of the steps, so instead of cloning this repo, simply
|
||||
download the notebook from the link above and load it up in VSCode
|
||||
(with the appropriate extensions installed)/Jupyter/JupyterLab and
|
||||
start running the cells one-by-one.
|
||||
|
||||
Note that you will need NVIDIA drivers, Python 3.10, and Git installed
|
||||
beforehand - simplified [step-by-step
|
||||
instructions](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
are available in the wiki (you'll only need steps 1, 2, & 3 ).
|
||||
|
||||
## **Manual Install**
|
||||
|
||||
### **pip**
|
||||
|
||||
See [Easy-peasy Windows install](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
in the wiki
|
||||
|
||||
### **Conda**
|
||||
|
||||
1. Install Anaconda3 (miniconda3 version) from here: https://docs.anaconda.com/anaconda/install/windows/
|
||||
|
||||
2. Install Git from here: https://git-scm.com/download/win
|
||||
|
||||
3. Launch Anaconda from the Windows Start menu. This will bring up a command window. Type all the remaining commands in this window.
|
||||
|
||||
4. Run the command:
|
||||
|
||||
```
|
||||
git clone https://github.com/lstein/stable-diffusion.git
|
||||
```
|
||||
|
||||
This will create stable-diffusion folder where you will follow the rest of the steps.
|
||||
|
||||
5. Enter the newly-created stable-diffusion folder. From this step forward make sure that you are working in the stable-diffusion directory!
|
||||
|
||||
```
|
||||
cd stable-diffusion
|
||||
```
|
||||
|
||||
6. Run the following two commands:
|
||||
|
||||
```
|
||||
conda env create -f environment.yaml (step 6a)
|
||||
conda activate ldm (step 6b)
|
||||
```
|
||||
|
||||
This will install all python requirements and activate the "ldm"
|
||||
environment which sets PATH and other environment variables properly.
|
||||
|
||||
7. Run the command:
|
||||
|
||||
```
|
||||
python scripts\preload_models.py
|
||||
```
|
||||
|
||||
This installs several machine learning models that stable diffusion requires.
|
||||
|
||||
Note: This step is required. This was done because some users may might be blocked by firewalls or have limited internet connectivity for the models to be downloaded just-in-time.
|
||||
|
||||
8. Now you need to install the weights for the big stable diffusion model.
|
||||
|
||||
- For running with the released weights, you will first need to set up an acount with Hugging Face (https://huggingface.co).
|
||||
- Use your credentials to log in, and then point your browser at https://huggingface.co/CompVis/stable-diffusion-v-1-4-original.
|
||||
- You may be asked to sign a license agreement at this point.
|
||||
- Click on "Files and versions" near the top of the page, and then click on the file named `sd-v1-4.ckpt`. You'll be taken to a page that
|
||||
prompts you to click the "download" link. Now save the file somewhere safe on your local machine.
|
||||
- The weight file is >4 GB in size, so
|
||||
downloading may take a while.
|
||||
|
||||
Now run the following commands from **within the stable-diffusion directory** to copy the weights file to the right place:
|
||||
|
||||
```
|
||||
mkdir -p models\ldm\stable-diffusion-v1
|
||||
copy C:\path\to\sd-v1-4.ckpt models\ldm\stable-diffusion-v1\model.ckpt
|
||||
```
|
||||
|
||||
Please replace `C:\path\to\sd-v1.4.ckpt` with the correct path to wherever you stashed this file. If you prefer not to copy or move the .ckpt file,
|
||||
you may instead create a shortcut to it from within `models\ldm\stable-diffusion-v1\`.
|
||||
|
||||
9. Start generating images!
|
||||
|
||||
```
|
||||
# for the pre-release weights
|
||||
python scripts\dream.py -l
|
||||
|
||||
# for the post-release weights
|
||||
python scripts\dream.py
|
||||
```
|
||||
|
||||
10. Subsequently, to relaunch the script, first activate the Anaconda command window (step 3),enter the stable-diffusion directory (step 5, `cd \path\to\stable-diffusion`), run `conda activate ldm` (step 6b), and then launch the dream script (step 9).
|
||||
|
||||
**Note:** Tildebyte has written an alternative ["Easy peasy Windows
|
||||
install"](https://github.com/lstein/stable-diffusion/wiki/Easy-peasy-Windows-install)
|
||||
which uses the Windows Powershell and pew. If you are having trouble with Anaconda on Windows, give this a try (or try it first!)
|
||||
|
||||
### Updating to newer versions of the script
|
||||
|
||||
This distribution is changing rapidly. If you used the `git clone` method (step 5) to download the stable-diffusion directory, then to update to the latest and greatest version, launch the Anaconda window, enter `stable-diffusion`, and type:
|
||||
|
||||
```
|
||||
git pull
|
||||
conda env update -f environment.yaml
|
||||
```
|
||||
|
||||
This will bring your local copy into sync with the remote one.

init_img // path to an initial image

ddim_eta // image randomness (eta=0.0 means the same seed always produces the same image)

To use the step callback, define a function that receives two arguments:

- Image GPU data
|

- The step number
|

|

To use the image callback, define a function of method that receives two arguments, an Image object
|

and the seed. You can then do whatever you like with the image, including converting it to
|
||||
different formats and manipulating it. For example:

image.save(f{'images/seed.png'})

The callback used by the prompt2png() can be found in ldm/dream_util.py. It contains code

to create the requested output directory, select a unique informative name for each image, and

write the prompt into the PNG metadata.

seed // seed for random number generator

cfg_scale // how strongly the prompt influences the image (7.5) (must be >1)
|

gfpgan_strength // strength for GFPGAN. 0.0 preserves image exactly, 1.0 replaces it completely

ddim_eta // image randomness (eta=0.0 means the same seed always produces the same image)

step_callback // a function or method that will be called each step

image_callback // a function or method that will be called each time an image is generated

To use the step callback, define a function that receives two arguments:

- Image GPU data

- The step number

To use the image callback, define a function of method that receives two arguments, an Image object

and the seed. You can then do whatever you like with the image, including converting it to

different formats and manipulating it. For example:

image.save(f{'images/seed.png'})

The callback used by the prompt2png() can be found in ldm/dream_util.py. It contains code

to create the requested output directory, select a unique informative name for each image, and

write the prompt into the PNG metadata.
