Installation with pip

Note

PyAutoFit requires Python 3.12 or later. If you are on Python 3.9, 3.10, or 3.11, pip install autofit will fail with a “no matching distribution” error. Upgrade Python to 3.12+ before installing.

We strongly recommend that you install PyAutoFit in a Python virtual environment, with the link attached describing what a virtual environment is and how to create one.

The latest version of PyAutoFit is installed via pip as follows (specifying the version as shown below ensures the installation has clean dependencies):

pip install autofit

If this raises no errors PyAutoFit is installed! If there is an error check out the troubleshooting section.

Next, clone the autofit_workspace (the line --depth 1 clones only the most recent branch on the autofit_workspace, reducing the download size):

cd /path/on/your/computer/you/want/to/put/the/autofit_workspace
git clone https://github.com/Jammy2211/autofit_workspace --depth 1
cd autofit_workspace

Run the welcome.py script to get started!

python3 welcome.py

Legacy Python versions

We dropped support for Python 3.9, 3.10, and 3.11 in release 2026.4.5.3 (April 2026). Pre-2026.4.5.3 releases on PyPI have been yanked, so they will not install via the standard pip install autofit command.

If you have an existing project that requires a pre-2026.4.5.3 version, you can still install it explicitly by pinning the version, e.g.:

pip install autofit==2025.10.6.1

Yanked releases remain available for explicit pins; only resolver-driven fallback is blocked.
