I have tried to run the Inference Inspection code in my windows machine with the given inference data as proposed in the README but I got the error:

I have tried installing OpenGL again but it did not solve the problem, I cannot find any sources for solving the dependency. How would you suggest me to solve it?

Hi there, I have only tested the code on Ubuntu. If you are on Windows and still have the problem, I would suggest trying Ubuntu.

I have tried the code on ubuntu and it works but on windows I am getting the same error. it looks it is because moderngl cannot create context with "egl" backend on windows. it works on linux but not on windows did you solve the problem on windows, or does anybody know any workaround for this...

Note: removing "egl" backend parameter and using default backend which is "wgl" (according to moderngl package site) creates the context but it gives another error

thanks in advance

If it works on Ubuntu why do you need it to work on Windows?
