To Reproduce
Steps to reproduce the behavior:

1. Install python 3.11
2. pip install monailabel

Expected behavior
monailabel should work with python 3.11

Other solutions
Downgrading to python 3.10 works in some environments, but often the python version cannot be influenced and this is only a temporary solution.

This issue with Python 3.11 also came up on the 3D Slicer forum. See https://discourse.slicer.org/t/openslide-python-not-working-when-trying-to-use-monailabel/33427.

The monai backend requires a specific openslide-python that does not have any Python 3.11 whl files on PyPI and the user fails to have all the dependencies to build it successfully from source.

Hi @AlexanderZeilmann,

Thanks for opening this issue.

As @jamesobutler, commented, MONAI Label hasn't been tested on Python 3.11 yet.

It is tested on Python 3.10 as you can see here: https://github.com/Project-MONAI/MONAI/blob/865972f7a791bf7b42efbcd87c8402bd865b329e/setup.cfg#L26

I'd recommend working with a Python env on version 3.9 or 3.10 or working with the MONAI Label Docker container: https://hub.docker.com/layers/projectmonai/monailabel/latest/images/sha256-e91d3a715c0381545bd88605b6ef61e73df30fe32f3fcc2c38e4c6e9a5a0f810?context=explore#!

More information about the Docker container is here: https://github.com/Project-MONAI/MONAILabel#development-version

Hope this helps,

[jamesobutler]

I have written up Project-MONAI/MONAI#7335 to encourage a newer version of python-openslide so that Python 3.11 can be used without running into issues of certain dependencies failing to build/install.
