Error when opening gui in 4-core codespace

[Adam-Albu]

I cloned this repo in a codespace using 32GB ram and 4 cores. I then I pre-trained the weights and installed the requirements. Then when I tried opening the GUI, this error occured:

I am seeing the same error too. PyOpenGL version problem??

I met the same problem and solved it, it is the pyopengl problem. I downgraded the pyopengl : pip install pyopengl . and then install python3-opengl package by apt-get: sudo apt-get install python3-opengl https://github.com/MPI-IS/mesh/issues/23
