Missing source file and GL error.

[xuxy09]

Seems an OpenGL error. Can you try a reinstallation with the instructions here: https://pyrender.readthedocs.io/en/latest/install/index.html#installing-osmesa?

Frustratingly, I tried to use OSMesa to reinstallation , but other errors appeared, which seem to be related to pyrender and have not been resolved. mmatl/pyrender#81

when using os.environ['PYOPENGL_PLATFORM'] = 'osmesa'

Traceback (most recent call last):

Hi, I just write a new "demo_nr.py" which does not rely on Pyrender. You can use it in the same way as "demo.py". Let me know if this works for you.

[LiuXinqi12]

It's working now, thank you very much!

Hi, does nerual_render only support render mesh in image of square size?

[MengHao666]

It's working now, thank you very much!

Hi, do u use neural_render in headless server? Have u succeeded in using pyrender in headless server?

You can check this with the author of neural render.

Yes, I can run pyrender on my server with OSMesa.

I met some problems and really hope u can help me.Can u give me your email address?In this way, we can have further talk.

How did you solve this problem? Just saying that it works now does not help others.

Hi, could you provide some suggestions on how to run pyrender on headless server with OSMesa? Thanks in advance!
