NumPy does not properly support sub-interpreters #27192
Description
Steps to reproduce:
I use the GeoPandas library which in turn uses NumPy but when I upload it to the server I get an error message. I've tried a few approaches but without success. Can anyone help me how to get around this?
Error message:
/site-packages/geopandas/geoseries.py:8: UserWarning: NumPy was imported from a Python sub-interpreter but NumPy does not properly support sub-interpreters. This will likely work for most users but might cause hard to track down issues or subtle bugs. A common user of the rare sub-interpreter feature is wsgi which also allows single-interpreter mode.

We don't support subinterpreters and currently do not plan to do so. My understanding is that doing so would require a substantial rewrite of significant portions of the low-level C code in NumPy to update our Python extension types from static types to heap types.
See #665 for the issue we usually cite for this.
Maybe look at gunicorn as a wsgi alternative that works without subinterpreters?
