Thanks a lot @vchoutas for your help :)
solved the problem by changing
os.environ['PYOPENGL_PLATFORM'] = 'egl'
in demo.py and inference.py to:
os.environ['PYOPENGL_PLATFORM'] = 'osmesa'

and also:

$ cd ..
$ git clone git@github.com:mmatl/pyopengl.git
$ pip install ./pyopengl

Hello, I use your method, but i get a new failed "AttributeError: 'NoneType' object has no attribute 'glGetError'" ! Can you tell me the pyrender's version?

[xiaoxingrunning]

你好，我使用你的方法，但我得到一个新的失败“AttributeError：'NoneType'对象没有属性'glGetError'”！你能告诉我pyrender的版本吗？

I have encountered the same problem as you. Have you solved it

[Schatz8]

我也，请问解决了吗

os.environ['PYOPENGL_PLATFORM'] = 'osmesa'
I try it，but there is a new problem. Could you help me?
