Hi, i want to run opengl without x-server, and i find that our code is the python version of this link, https://developer.nvidia.com/blog/egl-eye-opengl-visualization-without-x-server/
But saddly that i can not run main.py in my server, the error message is as follows:

apt install libgl1-mesa-dri libegl1-mesa libgbm1
pip install pyopengl numpy
pip install wheel
All the command that referenced in the readme have been excuted.
the nvidia-smi info is as follows:

Do you have any suggestions?
