Installing Manually

:fontawesome-brands-linux: Linux | :fontawesome-brands-apple: macOS | :fontawesome-brands-windows: Windows

!!! warning "This is for advanced Users"

**python experience is mandatory**

Introduction

!!! tip "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/Mac"
```
```bash
export INVOKEAI_ROOT="~/invokeai"
mkdir $INVOKEAI_ROOT
```
```
=== "Windows (Powershell)"
```
```bash
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.

=== "Linux/Mac" bash cd $INVOKEAI_ROOT python -m venv create .venv

=== "Windows" bash cd $INVOKEAI_ROOT python -m venv create .venv
Activate the new environment:

=== "Linux/Mac" bash source .venv/bin/activate

=== "Windows" bash .venv\script\activate If you get a permissions error at this point, run the command Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser and try activate again.

The command-line prompt should change to to show (.venv) 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)" bash pip install InvokeAI[xformers] --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117

=== "ROCm (AMD)" bash pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/rocm5.2

=== "CPU (Intel Macs & non-GPU systems)" bash pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu

=== "MPS (M1 and M2 Macs)" bash pip install InvokeAI --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu
Deactivate and reactivate your runtime directory so that the invokeai-specific commands become available in the environment

=== "Linux/Macintosh" bash deactivate && source .venv/bin/activate

=== "Windows" bash 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](050_INSTALLING_MODELS.md).
```

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 script invokeai. 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:

!!! example ""

!!! warning "Make sure that the virtual environment is activated, which should create `(.venv)` in front of your prompt!"

=== "CLI"

    ```bash
    invokeai
    ```

=== "local Webserver"

    ```bash
    invokeai --web
    ```

=== "Public Webserver"

    ```bash
    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](../features/CLI.md) 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)" bash pip install -e .[xformers] --use-pep517 --extra-index-url https://download.pytorch.org/whl/cu117

=== "ROCm (AMD)" bash pip install -e . --use-pep517 --extra-index-url https://download.pytorch.org/whl/rocm5.2

=== "CPU (Intel Macs & non-GPU systems)" bash pip install -e . --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu

=== "MPS (M1 and M2 Macs)" bash pip install -e . --use-pep517 --extra-index-url https://download.pytorch.org/whl/cpu

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.
