@JoerivanEngelen I looked into it and we are not able to support python 3.13 just yet.
The import of imod fails when it tries to install the dependencies, specifically when it installs the Numba package.
Numba doesn't support python 3.13 because on of its dependecies doesnt support it yet.

For now we can only clearly mention in the documentation that we don't support 3.13 at the moment

Ah thanks for looking into this. In my quick search on the internet I read that numba already has some pre-releases out for python 3.13, so I expect it won't take too long for them to release a new version that supports python 3.13.

I must say this error message looks quite clumsy though, since apparently Path objects cannot be used as contexts since python 3.9(!). It's also throwing warnings. I'll create a subissue for this specific error, as it is still worthy to fix but maybe less critical now. We can already fix this in preparation of the next numba release.

Update: Recently Numba got a release that supports Python 3.13. See https://numba.readthedocs.io/en/stable/release/0.61.0-notes.html
