Hi @maaa-a

It looks like there are issues with your Python environment and the installation of numpy.

Are you using conda or virtualenv? Can you check the version of Python and numpy you are using? To get the values, start a new R session, pick the environment to use with reticulate (e.g. reticulate::use_virtualenv('igt')) and then run reticulate::py_config().

If you have an older version of numpy, updating may solve the issue

"I've been using the latest versions of Python and numpy. If I need to use another version.
version: 3.12.4 (tags/v3.12.4:8e8a4ba, Jun 6 2024, 19:30:16)
numpy_version: 2.0.0

It seems like numpy 2.0 has introduced some non-breaking changes. Try downgrading numpy (e.g. reticulate::py_install('numpy<2.0' ) )

I have created an issue on the Python project (KlugerLab/GeneTrajectory-python#12) to try and make the package compatible with numpy 2.0 and 1.26.
