Since I recently updated my Mac to Big Sur I keep having errors when trying to run a python program, more specifically with OpenGL. To be specific, I get these two errors:
Traceback (most recent call last):
File "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/OpenGL/platform/darwin.py", line 38, in GL

OSError: ('dlopen(OpenGL, 10): image not found', 'OpenGL', None)
During handling of the above exception, another exception occurred:

I have tried to see where the issue is by using another proposed solution (first answer) on this forum as described here: Unable to import opengl.gl in python on macos
However, I am not sure if I have done this with the correct file path. Could someone indicate what the filepath in my case would be? Thanks a lot!
