Add support to Python 3.10 and 3.11. Before that – update documentation

Author: GegznaVCreated Sep 17, 2023Updated Aug 14, 2025

Describe the bug

auto-sklearn does not install in Python 3.10 and 3.11-based environments.

Before this issue is fixed (as it will take some time), please update the documentation, stating which exact Python versions are really supported (now it is stated that "Python (>=3.7)" which implies that there are should be no issues with 3.10 and 3.11).

To Reproduce

Create a new Python 3.10 or Python 3.11-based conda environment.

bash

conda create -n py310 python=3.10

Activate the environment:

bash

conda activate py310

Try to install auto-sklearn there. I use mamba here as it gives the easiest-to-understand error message in a reasonable amount of time (I tired pip and conda too with no success):

Expected behavior

Install without errors with Python 3.100 and 3.11.

Actual behavior, stacktrace or logfile
