Fails to add custom python packages under Linux #76

Closed Necrorez closed 3 weeks ago

Necrorez commented 4 weeks ago

I'm experiencing an issue when trying to install and use Python packages (Debian 11, Debian 12, Arch) (specifically numpy) in a Godot 4.3 project. I followed the steps from the "Installing packages for python" documentation, but I encountered the following error when attempting to use numpy:

ImportError: Error importing numpy: you should not try to import numpy from
    its source directory; please exit the numpy source tree, and relaunch
    your python interpreter from there.

Error Traceback:

Other packages seem to work. But numpy is one of the most essential (OpenCV, Pandas, SciPy, scikit-learn). Also I've tried all the possible releases. Building from source also fails on my machines.

Works with the numpy fix. Thanks.
