[Python] 'GLXPlatform' object has no attribute 'OSMesa'

I am testing whether OSMesa functions properly, but I encountered the following error. How can this error be resolved?

The full error message:

Minimal reproducible example:

from OpenGL import osmesa

ctx = osmesa.OSMesaCreateContext(osmesa.OSMESA_RGBA, None)


My environment as follows:

pyrender==0.1.45
OpenGL==3.1.0
