The "One-Click" Installer

Introduction

The one-click installer is a shell script that attempts to automate every step needed to install and run InvokeAI on a stock computer running recent versions of Linux, MacOSX or Windows.

Before you begin, make sure that you meet the hardware requirements and has the appropriate GPU drivers installed. In particular, if you are a Linux user with an AMD GPU installed, you may need to install the ROCm driver.

Installation requires roughly 18G of free disk space to load the libraries and recommended model weights files.

Walk through

Though there are multiple steps, there really is only one click involved to kick off the process.

1. The 1-click installer is distributed in ZIP files. Download the one that is appropriate for your operating system:

!!! todo "Change the URLs after release"

- [invokeAI-mac.zip](https://github.com/invoke-ai/InvokeAI/releases/download/2.1.3-rc1/invokeAI-mac.zip)
- [invokeAI-linux.zip](https://github.com/invoke-ai/InvokeAI/releases/download/2.1.3-rc1/invokeAI-linux.zip)
- [invokeAI-windows.zip](https://github.com/invoke-ai/InvokeAI/releases/download/2.1.3-rc1/invokeAI-windows.zip)

2. Unpack the zip file into a directory that has at least 18G of free space. Do not unpack into a directory that has an earlier version of InvokeAI.

   This will create a new directory named "InvokeAI". This example shows how this would look using the unzip command-line tool, but you may use any graphical or command-line Zip extractor:

   C:\Documents\Linco> unzip invokeAI-windows.zip
   Archive:  C: \Linco\Downloads\invokeAI-linux.zip
   creating: invokeAI\
   inflating: invokeAI\install.bat
   inflating: invokeAI\readme.txt     
   

3. If you are using a desktop GUI, double-click the installer file. It will be named install.bat on Windows systems and install.sh on Linux and Macintosh systems.

4. Alternatively, form the command line, run the shell script or .bat file:

   C:\Documents\Linco> cd invokeAI
   C:\Documents\Linco> install.bat
   

5. Sit back and let the install script work. It will install various binary requirements including Conda, Git and Python, then download the current InvokeAI code and install it along with its dependencies.

6. After installation completes, the installer will launch a script called preload_models.py, which will guide you through the first-time process of selecting one or more Stable Diffusion model weights files, downloading and configuring them.

   Note that the main Stable Diffusion weights file is protected by a license agreement that you must agree to in order to use. The script will list the steps you need to take to create an account on the official site that hosts the weights files, accept the agreement, and provide an access token that allows InvokeAI to legally download and install the weights files.

   If you have already downloaded the weights file(s) for another Stable Diffusion distribution, you may skip this step (by selecting "skip" when prompted) and configure InvokeAI to use the previously-downloaded files. The process for this is described in [INSTALLING_MODELS.md].

7. The script will now exit and you'll be ready to generate some images. The invokeAI directory will contain numerous files. Look for a shell script named invoke.sh (Linux/Mac) or invoke.bat (Windows). Launch the script by double-clicking it or typing its name at the command-line:

C:\Documents\Linco\invokeAI> cd invokeAI
C:\Documents\Linco\invokeAI> invoke.bat

The invoke.bat (invoke.sh) script will give you the choice of starting (1) the command-line interface, or (2) the web GUI. If you start the latter, you can load the user interface by pointing your browser at http://localhost:9090.

The invoke script also offers you a third option labeled "open the developer console". If you choose this option, you will be dropped into a command-line interface in which you can run python commands directly, access developer tools, and launch InvokeAI with customized options. To do the latter, you would launch the script scripts/invoke.py as shown in this example:

python scripts\invoke.py --web --max_load_models=3 \
    --model=waifu-1.3 --steps=30 --outdir=C:/Documents/AIPhotos

These options are described in detail in the Command-Line Interface documentation.

Updating to newer versions

This section describes how to update InvokeAI to new versions of the software.

Updating the stable version

This distribution is changing rapidly, and we add new features on a daily basis. To update to the latest released version (recommended), run the update.sh (Linux/Mac) or update.bat (Windows) scripts. This will fetch the latest release and re-run the preload_models script to download any updated models files that may be needed. You can also use this to add additional models that you did not select at installation time.

Updating to the development version

There may be times that there is a feature in the development branch of InvokeAI that you'd like to take advantage of. Or perhaps there is a branch that corrects an annoying bug. To do this, you will use the developer's console.

From within the invokeAI directory, run the command invoke.sh (Linux/Mac) or invoke.bat (Windows) and selection option (3) to open the developers console. Then run the following command to get the development branch:

git checkout development
git pull
conda env update

You can now close the developer console and run invoke as before. If you get complaints about missing models, then you may need to do the additional step of running preload_models.py. This happens relatively infrequently. To do this, simply open up the developer's console again and type python scripts/preload_models.py.

Troubleshooting

If you run into problems during or after installation, the InvokeAI team is available to help you. Either create an Issue at our GitHub site, or make a request for help on the "bugs-and-support" channel of our Discord server. We are a 100% volunteer organization, but typically somebody will be available to help you within 24 hours, and often much sooner.
