Rendering environment error

[LSQsjtu]

While testing the garment simulation, I encountered an error when rendering the garment garment_specification.json.

It appears to be an error related to the pyrender version. Could you provide any assistance with the installation of pyrender and PyOpenGL?

I am using Ubuntu 20.04.6 LTS with CUDA 11.3. My Python version is 3.10, Pyrender is at version 0.1.45, and PyOpenGL is at version 3.1.0.

Hi, sorry for delay in my replies

At first glance it seems like versions conflict

I will double check within a few days and return back to you

@LSQsjtu again, many apologies for delay, unfortunately, I have limited capacity to answer the issues in timely manner, but if you still encounter the problem, here is what I found.

Here is my setup with versions of libs which successfully render your example: python 3.10.6 CUDA 12.5 pyrender 0.1.45 PyOpenGL 3.1.0 Pillow 10.1.0 trimesh 4.0.7 imageio 2.33.1

And, I'm using Windows as my OS. It seems like the setup is the same except for CUDA version and OS, so maybe you could try some suggestions from pyrender community: https://github.com/mmatl/pyrender/issues/148#issuecomment-844102585 https://github.com/mmatl/pyrender/issues/86

Please, let me know if any of these help!

Thanks for your reply. It works on Windows, but is still not working on my Linux machine. The rendering error might be my environment error in my environment. Because the EGL is not working on my Linux machine, and I change to OSMesa.

Unfortunately, I've never tested this on Linux, but I might be soon I will update this issue if any new info shows up
