The InvokeAI Source Installer#
The source 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, 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.
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.
Though there are multiple steps, there really is only one click involved to kick off the process.
The source installer is distributed in ZIP files. Go to the latest release, and look for a series of files named:
Download the one that is appropriate for your operating system.
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
unzipcommand-line tool, but you may use any graphical or command-line Zip extractor:
If you are a macOS user, 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 here: https://www.freecodecamp.org/news/install-xcode-command-line-tools/
If you are using a desktop GUI, double-click the installer file. It will be named
install.baton Windows systems and
install.shon Linux and Macintosh systems.
Alternatively, from the command line, run the shell script or .bat file:
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.
Be aware that some of the library download and install steps take a long time. In particular, the
pytorchpackage is quite large and often appears to get "stuck" at 99.9%. Similarly, the
pip installing requirementsstep may appear to hang. 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.
After installation completes, the installer will launch a script called
configure_invokeai.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.
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.bat(Windows). Launch the script by double-clicking it or typing its name at the command-line:
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.
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
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.
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 out library conflicts. There are
two steps you can take to clear this problem. Both of these are done
from within the "developer's console", which you can get to by
invoke.bat) and selecting launch option
- Remove the previous
invokeaienvironment completely. From within the developer's console, give the command
conda env remove -n invokeai. This will delete previous files installed by
Then exit from the developer's console and launch the script
update.bat). This will download the most recent
InvokeAI (including bug fixes) and reinstall the environment.
You should then be able to run
- If this doesn't work, you can try cleaning your system's conda
cache. This is slightly more extreme, but won't interfere with
any other python-based programs installed on your computer.
From the developer's console, run the command
conda clean -aand answer "yes" to all prompts.
After this is done, run
update.sh and try again as before.
"Corrupted configuration file."_ Everything seems to install ok, but
invoke complains of a corrupted configuration file and goes calls
configure_invokeai.py to fix, but this doesn't fix the problem.
This issue is often caused by a misconfigured configuration directive
.invokeai initialization file that contains startup settings.
This can be corrected by fixing the offending line.
.invokeai. It is a small text file located in your home
~/.invokeai on Mac and Linux systems, and
name*\.invokeai on Windows systems. Open it with a text editor
(e.g. Notepad on Windows, TextEdit on Macs, or
nano on Linux)
and look for the lines starting with
An example is here:
There should not be whitespace before or after the directory paths, and the paths should not end with slashes:
--root="/home/lstein/invokeai " # wrong! no whitespace here --root="/home\lstein\invokeai\" # wrong! shouldn't end in a slash
Fix the problem with your text editor and save as a plain text file. This should clear the issue.
If none of these maneuvers fixes the problem then please report the problem to the InvokeAI Issues section, or visit our Discord Server for interactive assistance.
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.bat (Windows) scripts. This will fetch the latest
release and re-run the
configure_invokeai 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.
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
configure_invokeai.py. This happens relatively infrequently. To do this,
simply open up the developer's console again and type
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.
