Which Python versions are supported? Maybe it should be added to the README...

Hi,

thanks for posting the issue. I can reproduce this on a clean install of Python3.12.

Our test currently run for Python 3.8 to 3.11, so I would consider this as suuported. Expanding to 3.12 would be great.

After a bit of research seems its due to some deprecation of the importlib. See here.

So I think we need to check if we can use shapely>2.0 and since we rely on onnxruntime package and it does not support 3.12 this might become a blocker for now: https://github.com/microsoft/onnxruntime/issues/17842

Added a section in the README about supported python versions. See this commit

Thanks! Maybe a requirements.txt wouldn't do any harm as well...

Hi, We are using poetry to manage the dependencies.

However if you want to can install the export plugin and export the dependencies to a requirements.txt as described here with:

poetry export -f requirements.txt --output requirements.txt
