Introduction#

Conda

As of InvokeAI v2.3.0 installation using the conda package manager is no longer being supported. It will likely still work, but we are not testing this installation method.

On Windows systems, you are encouraged to install and use the PowerShell, which provides compatibility with Linux and Mac shells and nice features such as command-line completion.

Prerequisites#

Before you start, make sure you have the following preqrequisites installed. These are described in more detail in Automated Installation, and in many cases will already be installed (if, for example, you have used your system for gaming):

Python

version 3.9 or 3.10 (3.11 is not recommended).
CUDA Tools

For those with NVidia GPUs, you will need to install the CUDA toolkit and optionally the XFormers library.
ROCm Tools

For Linux users with AMD GPUs, you will need to install the ROCm toolkit. Note that InvokeAI does not support AMD GPUs on Windows systems due to lack of a Windows ROCm library.
Visual C++ Libraries

Windows users must install the free Visual C++ libraries from Microsoft
The Xcode command line tools

for Macintosh users. Instructions are available at Free Code Camp
- Macintosh users may also need to run the Install Certificates command if model downloads give lots of certificate errors. Run: /Applications/Python\ 3.10/Install\ Certificates.command

Installation Walkthrough#

To install InvokeAI with virtual environments and the PIP package manager, please follow these steps:

Please make sure you are using Python 3.9 or 3.10. The rest of the install procedure depends on this and will not work with other versions:
```
python -V
```
Create a directory to contain your InvokeAI library, configuration files, and models. This is known as the "runtime" or "root" directory, and often lives in your home directory under the name invokeai.

Please keep in mind the disk space requirements - you will need at least 20GB for the models and the virtual environment. From now on we will refer to this directory as INVOKEAI_ROOT. For convenience, the steps below create a shell variable of that name which contains the path to HOME/invokeai.
Linux/MacWindows (Powershell)
export INVOKEAI_ROOT=~/invokeai mkdir $INVOKEAI_ROOT
Set-Variable -Name INVOKEAI_ROOT -Value $Home/invokeai mkdir $INVOKEAI_ROOT
Enter the root (invokeai) directory and create a virtual Python environment within it named .venv. If the command python doesn't work, try python3. Note that while you may create the virtual environment anywhere in the file system, we recommend that you create it within the root directory as shown here. This makes it possible for the InvokeAI applications to find the model data and configuration. If you do not choose to install the virtual environment inside the root directory, then you must set the INVOKEAI_ROOT environment variable in your shell environment, for example, by editing ~/.bashrc or ~/.zshrc files, or setting the Windows environment variable using the Advanced System Settings dialogue. Refer to your operating system documentation for details.
```
cd $INVOKEAI_ROOT
python -m venv .venv --prompt InvokeAI
```
Activate the new environment:
Linux/MacWindows
source .venv/bin/activate
.venv\Scripts\activate
If you get a permissions error at this point, run this command and try again

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
The command-line prompt should change to to show (InvokeAI) at the beginning of the prompt. Note that all the following steps should be run while inside the INVOKEAI_ROOT directory
Make sure that pip is installed in your virtual environment and up to date:
```
python -m pip install --upgrade pip
```

Install the InvokeAI Package. The --extra-index-url option is used to select among CUDA, ROCm and CPU/MPS drivers as shown below:

CUDA (NVidia)ROCm (AMD)CPU (Intel Macs & non-GPU systems)MPS (M1 and M2 Macs)

pip install "InvokeAI[xformers]" --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117

pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/rocm5.4.2

pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu

pip install InvokeAI --use-pep517

Deactivate and reactivate your runtime directory so that the invokeai-specific commands become available in the environment
Linux/MacintoshWindows
deactivate && source .venv/bin/activate
deactivate .venv\Scripts\activate
Set up the runtime directory

In this step you will initialize your runtime directory with the downloaded models, model config files, directory for textual inversion embeddings, and your outputs.
```
invokeai-configure
```
The script invokeai-configure will interactively guide you through the process of downloading and installing the weights files needed for InvokeAI. Note that the main Stable Diffusion weights file is protected by a license agreement that you have to agree to. The script will list the steps you need to take to create an account on the 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 get an error message about a module not being installed, check that the invokeai environment is active and if not, repeat step 5.

Tip

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.
Run the command-line- or the web- interface:

From within INVOKEAI_ROOT, activate the environment (with source .venv/bin/activate or .venv\scripts\activate), and then run the scriptinvokeai. If the virtual environment you selected is NOT inside INVOKEAI_ROOT, then you must specify the path to the root directory by adding--root_dir \path\to\invokeai` to the commands below:
Make sure that the virtual environment is activated, which should create (.venv) in front of your prompt!
CLIlocal WebserverPublic Webserver
invokeai
invokeai --web
invokeai --web --host 0.0.0.0
If you choose the run the web interface, point your browser at http://localhost:9090 in order to load the GUI.
Tip

You can permanently set the location of the runtime directory by setting the environment variable INVOKEAI_ROOT to the path of the directory. As mentioned previously, this is highly recommended* if your virtual environment is located outside of your runtime directory.
Render away!

Browse the features section to learn about all the things you can do with InvokeAI.
Subsequently, to relaunch the script, activate the virtual environment, and then launch invokeai command. If you forget to activate the virtual environment you will most likeley receive a command not found error.

Warning

Do not move the runtime directory after installation. The virtual environment will get confused if the directory is moved.
Other scripts

The Textual Inversion script can be launched with the command:
```
invokeai-ti --gui
```
Similarly, the Model Merging script can be launched with the command:
```
invokeai-merge --gui
```
Leave off the --gui option to run the script using command-line arguments. Pass the --help argument to get usage instructions.

Developer Install#

If you have an interest in how InvokeAI works, or you would like to add features or bugfixes, you are encouraged to install the source code for InvokeAI. For this to work, you will need to install the git source code management program. If it is not already installed on your system, please see the Git Installation Guide

From the command line, run this command:
```
git clone https://github.com/invoke-ai/InvokeAI.git
```
This will create a directory named InvokeAI and populate it with the full source code from the InvokeAI repository.
Activate the InvokeAI virtual environment as per step (4) of the manual installation protocol (important!)
Enter the InvokeAI repository directory and run one of these commands, based on your GPU:
CUDA (NVidia)ROCm (AMD)CPU (Intel Macs & non-GPU systems)MPS (M1 and M2 Macs)
pip install -e .[xformers] --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117
pip install -e . --use-pep517 --extra-index-url https://download.pytorch.org/whl/rocm5.4.2
pip install -e . --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu
pip install -e . --use-pep517
Be sure to pass -e (for an editable install) and don't forget the dot ("."). It is part of the command.

You can now run invokeai and its related commands. The code will be read from the repository, so that you can edit the .py source files and watch the code's behavior change.
If you wish to contribute to the InvokeAI project, you are encouraged to establish a GitHub account and "fork" https://github.com/invoke-ai/InvokeAI into your own copy of the repository. You can then use GitHub functions to create and submit pull requests to contribute improvements to the project.

Please see Contributing for hints on getting started.

Unsupported Conda Install#

Congratulations, you found the "secret" Conda installation instructions. If you really really want to use Conda with InvokeAI you can do so using this unsupported recipe:

mkdir ~/invokeai
conda create -n invokeai python=3.10
conda activate invokeai
pip install InvokeAI[xformers] --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117
invokeai-configure --root ~/invokeai
invokeai --root ~/invokeai --web

The pip install command shown in this recipe is for Linux/Windows systems with an NVIDIA GPU. See step (6) above for the command to use with other platforms/GPU combinations. If you don't wish to pass the --root argument to invokeai with each launch, you may set the environment variable INVOKEAI_ROOT to point to the installation directory.

Note that if you run into problems with the Conda installation, the InvokeAI staff will not be able to help you out. Caveat Emptor!
