--- title: Installing with the Automated Installer --- # InvokeAI Automated Installation ## Introduction The automated installer is a Python script that automates the steps needed to install and run InvokeAI on a stock computer running recent versions of Linux, MacOS or Windows. It will leave you with a version that runs a stable version of InvokeAI with the option to upgrade to experimental versions later. ## Walk through 1. **Hardware Requirements**: Make sure that your system meets the [hardware requirements](../index.md#hardware-requirements) and has the appropriate GPU drivers installed. For a system with an NVIDIA card installed, you will need to install the CUDA driver, while AMD-based cards require the ROCm driver. In most cases, if you've already used the system for gaming or other graphics-intensive tasks, the appropriate drivers will already be installed. If unsure, check the [GPU Driver Guide](030_INSTALL_CUDA_AND_ROCM.md) !!! info "Required Space" Installation requires roughly 18G of free disk space to load the libraries and recommended model weights files. Regardless of your destination disk, your *system drive* (`C:\` on Windows, `/` on macOS/Linux) requires at least 6GB of free disk space to download and cache python dependencies. NOTE for Linux users: if your temporary directory is mounted as a `tmpfs`, ensure it has sufficient space. 2. **Software Requirements**: Check that your system has an up-to-date Python installed. To do this, open up a command-line window ("Terminal" on Linux and Macintosh, "Command" or "Powershell" on Windows) and type `python --version`. If Python is installed, it will print out the version number. If it is version `3.9.1` or `3.10.x`, you meet requirements. !!! warning "What to do if you have an unsupported version" Go to [Python Downloads](https://www.python.org/downloads/) and download the appropriate installer package for your platform. We recommend [Version 3.10.9](https://www.python.org/downloads/release/python-3109/), which has been extensively tested with InvokeAI. At this time we do not recommend Python 3.11. _Please select your platform in the section below for platform-specific setup requirements._ === "Windows" During the Python configuration process, look out for a checkbox to add Python to your PATH and select it. If the install script complains that it can't find python, then open the Python installer again and choose "Modify" existing installation. Installation requires an up to date version of the Microsoft Visual C libraries. Please install the 2015-2022 libraries available here: https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170 Please double-click on the file `WinLongPathsEnabled.reg` and accept the dialog box that asks you if you wish to modify your registry. This activates long filename support on your system and will prevent mysterious errors during installation. === "Linux" To install an appropriate version of Python on Ubuntu 22.04 and higher, run the following: ``` sudo apt update sudo apt install -y python3 python3-pip python3-venv sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3.10 3 ``` On Ubuntu 20.04, the process is slightly different: ``` sudo apt update sudo apt install -y software-properties-common sudo add-apt-repository -y ppa:deadsnakes/ppa sudo apt install python3.10 python3-pip python3.10-venv sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3.10 3 ``` Both `python` and `python3` commands are now pointing at Python3.10. You can still access older versions of Python by calling `python2`, `python3.8`, etc. Linux systems require a couple of additional graphics libraries to be installed for proper functioning of `python3-opencv`. Please run the following: `sudo apt update && sudo apt install -y libglib2.0-0 libgl1-mesa-glx` === "Mac" After installing Python, you may need to run the following command from the Terminal in order to install the Web certificates needed to download model data from https sites. If you see lots of CERTIFICATE ERRORS during the last part of the install, this is the problem, and you can fix it with this command: `/Applications/Python\ 3.10/Install\ Certificates.command` You may need to install the Xcode command line tools. These are a set of tools that are needed to run certain applications in a Terminal, including InvokeAI. This package is provided directly by Apple. To install, open a terminal window and run `xcode-select --install`. You will get a macOS system popup guiding you through the install. If you already have them installed, you will instead see some output in the Terminal advising you that the tools are already installed. More information can be found at [FreeCode Camp](https://www.freecodecamp.org/news/install-xcode-command-line-tools/) 3. **Download the Installer**: The InvokeAI installer is distributed as a ZIP files. Go to the [latest release](https://github.com/invoke-ai/InvokeAI/releases/latest), and look for a file named: - InvokeAI-installer-v2.X.X.zip where "2.X.X" is the latest released version. The file is located at the very bottom of the release page, under **Assets**. 4. **Unpack the installer**: Unpack the zip file into a convenient directory. This will create a new directory named "InvokeAI-Installer". When unpacked, the directory will look like this:
![zipfile-screenshot](../assets/installer-walkthrough/unpacked-zipfile.png)
5. **Launch the installer script from the desktop**: If you are using a desktop GUI, double-click the installer file appropriate for your platform. It will be named `install.bat` on Windows systems and `install.sh` on Linux and Macintosh systems. Be aware that your system's file browser may suppress the display of the file extension. On Windows systems if you get an "Untrusted Publisher" warning. Click on "More Info" and then select "Run Anyway." You trust us, right? 6. **[Alternative] Launch the installer script from the command line**: Alternatively, from the command line, run the shell script or .bat file: ```cmd C:\Documents\Linco> cd InvokeAI-Installer C:\Documents\Linco\invokeAI> install.bat ``` 7. **Select the location to install InvokeAI**: The script will ask you to choose where to install InvokeAI. Select a directory with at least 18G of free space for a full install. InvokeAI and all its support files will be installed into a new directory named `invokeai` located at the location you specify.
![confirm-install-directory-screenshot](../assets/installer-walkthrough/confirm-directory.png)
- The default is to install the `invokeai` directory in your home directory, usually `C:\Users\YourName\invokeai` on Windows systems, `/home/YourName/invokeai` on Linux systems, and `/Users/YourName/invokeai` on Macintoshes, where "YourName" is your login name. - The script uses tab autocompletion to suggest directory path completions. Type part of the path (e.g. "C:\Users") and press ++tab++ repeatedly to suggest completions. 8. **Select your GPU**: The installer will autodetect your platform and will request you to confirm the type of GPU your graphics card has. On Linux systems, you will have the choice of CUDA (NVidia cards), ROCm (AMD cards), or CPU (no graphics acceleration). On Windows, you'll have the choice of CUDA vs CPU, and on Macs you'll be offered CPU only. When you select CPU on M1 or M2 Macintoshes, you will get MPS-based graphics acceleration without installing additional drivers. If you are unsure what GPU you are using, you can ask the installer to guess.

9. **Watch it go!**: Sit back and let the install script work. It will install the third-party libraries needed by InvokeAI and the application itself. Be aware that some of the library download and install steps take a long time. In particular, the `pytorch` package is quite large and often appears to get "stuck" at 99.9%. Have patience and the installation step will eventually resume. However, there are occasions when the library install does legitimately get stuck. If you have been waiting for more than ten minutes and nothing is happening, you can interrupt the script with ^C. You may restart it and it will pick up where it left off. 10. **Post-install Configuration**: After installation completes, the installer will launch the configuration script, which will guide you through the first-time process of selecting one or more Stable Diffusion model weights files, downloading and configuring them. We provide a list of popular models that InvokeAI performs well with. However, you can add more weight files later on using the command-line client or the Web UI. See [Installing Models](050_INSTALLING_MODELS.md) for details.
![downloading-models-screenshot](../assets/installer-walkthrough/downloading-models.png)
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](050_INSTALLING_MODELS.md). 11. **Running InvokeAI for the first time**: The script will now exit and you'll be ready to generate some images. Look for the directory `invokeai` installed in the location you chose at the beginning of the install session. 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: ```cmd C:\Documents\Linco> 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, (2) the web GUI, (3) textual inversion training, and (4) model merging. - By default, the script will launch the web interface. When you do this, you'll see a series of startup messages ending with instructions to point your browser at http://localhost:9090. Click on this link to open up a browser and start exploring InvokeAI's features. 12. **InvokeAI Options**: You can launch InvokeAI with several different command-line arguments that customize its behavior. For example, you can change the location of the image output directory, or select your favorite sampler. See the [Command-Line Interface](../features/CLI.md) for a full list of the options. - To set defaults that will take effect every time you launch InvokeAI, use a text editor (e.g. Notepad) to exit the file `invokeai\invokeai.init`. It contains a variety of examples that you can follow to add and modify launch options. - The launcher script also offers you an 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. !!! warning "Do not move or remove the `invokeai` directory" The `invokeai` directory contains the `invokeai` application, its configuration files, the model weight files, and outputs of image generation. Once InvokeAI is installed, do not move or remove this directory." ## Troubleshooting ### _Package dependency conflicts_ If you have previously installed InvokeAI or another Stable Diffusion package, the installer may occasionally pick up outdated libraries and either the installer or `invoke` will fail with complaints about library conflicts. In this case, run the `invoke.sh`/`invoke.bat` command and enter the Developer's Console by picking option (5). This will take you to a command-line prompt. Then give this command: `pip install InvokeAI --force-reinstall` This should fix the issues. ### InvokeAI runs extremely slowly on Linux or Windows systems The most frequent cause of this problem is when the installation process installed the CPU-only version of the torch machine-learning library, rather than a version that takes advantage of GPU acceleration. To confirm this issue, look at the InvokeAI startup messages. If you see a message saying ">> Using device CPU", then this is what happened. To fix this problem, first determine whether you have an NVidia or an AMD GPU. The former uses the CUDA driver, and the latter uses ROCm (only available on Linux). Then run the `invoke.sh`/`invoke.bat` command and enter the Developer's Console by picking option (5). This will take you to a command-line prompt. Then type the following commands: === "NVIDIA System" ```bash pip install torch torchvision --force-reinstall --extra-index-url https://download.pytorch.org/whl/cu117 pip install xformers ``` === "AMD System" ```bash pip install torch torchvision --force-reinstall --extra-index-url https://download.pytorch.org/whl/rocm5.2 ``` ### Corrupted configuration file Everything seems to install ok, but `invokeai` complains of a corrupted configuration file and goes back into the configuration process (asking you to download models, etc), but this doesn't fix the problem. This issue is often caused by a misconfigured configuration directive in the `invokeai\invokeai.init` initialization file that contains startup settings. The easiest way to fix the problem is to move the file out of the way and re-run `invokeai-configure`. Enter the developer's console (option 3 of the launcher script) and run this command: ```cmd invokeai-configure --root=. ``` Note the dot (.) after `--root`. It is part of the command. _If none of these maneuvers fixes the problem_ then please report the problem to the [InvokeAI Issues](https://github.com/invoke-ai/InvokeAI/issues) section, or visit our [Discord Server](https://discord.gg/ZmtBAhwWhy) for interactive assistance. ### Other Problems If you run into problems during or after installation, the InvokeAI team is available to help you. Either create an [Issue](https://github.com/invoke-ai/InvokeAI/issues) at our GitHub site, or make a request for help on the "bugs-and-support" channel of our [Discord server](https://discord.gg/ZmtBAhwWhy). We are a 100% volunteer organization, but typically somebody will be available to help you within 24 hours, and often much sooner. ## Updating to newer versions This distribution is changing rapidly, and we add new features regularly. Releases are announced at http://github.com/invoke-ai/InvokeAI/releases, and at https://pypi.org/project/InvokeAI/ To update to the latest released version (recommended), follow these steps: 1. Start the `invoke.sh`/`invoke.bat` launch script from within the `invokeai` root directory. 2. Choose menu item (6) "Developer's Console". This will launch a new command line. 3. Type the following command: ```bash pip install InvokeAI --upgrade ``` 4. Watch the installation run. Once it is complete, you may exit the command line by typing `exit`, and then start InvokeAI from the launch script as per usual. Alternatively, if you wish to get the most recent unreleased development version, perform the same steps to enter the developer's console, and then type: ```bash pip install https://github.com/invoke-ai/InvokeAI/archive/refs/heads/main.zip ```
