Manual Install#
Warning
Python experience is mandatory.
If you want to use Invoke locally, you should probably use the launcher.
If you want to contribute to Invoke, instead follow the dev environment guide.
InvokeAI is distributed as a python package on PyPI, installable with pip
. There are a few things that are handled by the installer and launcher that you'll need to manage manually, described in this guide.
Requirements#
Before you start, go through the installation requirements.
Walkthrough#
-
Create a directory to contain your InvokeAI library, configuration files, and models. This is known as the "runtime" or "root" directory, and typically lives in your home directory under the name
invokeai
. -
Enter the root directory and create a virtual Python environment within it named
.venv
.Virtual Environment Location
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 allows the application to automatically detect its data directories.
If you choose a different location for the venv, then you must set the
INVOKEAI_ROOT
environment variable or specify the root directory using the--root
CLI arg. -
Activate the new environment:
Permissions Error (Windows)
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)
, indicating the venv is active. -
Make sure that pip is installed in your virtual environment and up to date:
-
Install the InvokeAI Package. The base command is
pip install InvokeAI --use-pep517
, but you may need to change this depending on your system and the desired features.- You may need to provide an extra index URL. Select your platform configuration using this tool on the PyTorch website. Copy the
--extra-index-url
string from this and append it to your install command.
- If you have a CUDA GPU and want to install with
xformers
, you need to add an option to the package name. Note thatxformers
is not strictly necessary. PyTorch includes an implementation of the SDP attention algorithm with similar performance for most GPUs.
- You may need to provide an extra index URL. Select your platform configuration using this tool on the PyTorch website. Copy the
-
Deactivate and reactivate your venv so that the invokeai-specific commands become available in the environment:
-
Run the application:
Run
invokeai-web
to start the UI. You must activate the virtual environment before running the app.Warning
If the virtual environment is not inside the root directory, then you must specify the path to the root directory with
--root \path\to\invokeai
or theINVOKEAI_ROOT
environment variable.
