pyrender: Failed rendering frame

[yosagaf]

I'm trying to launch the demo and i'm still getting this error.
What could be the solution ?

Thanks.

Try to include this argc --visualize False, e.g. python xxx --visualize False

the author says:
By default, running the demo uses pyrender to render the sequence to a video, however this causes problems for certain configurations (e.g. if running the code remotely). In this case try running the demo with an additional flag --visualize False to disable the visualization. The animated meshes are then still stored to the output directory and can be viewed or rendered with another tool.

Thanks guys, I can see the meshes with online 3D viewer.
I'm using Linux machine, is there a solution to render the sequence video.

@liyuanyaun @yosagaf
Had this errors:
pyrender: Failed rendering frame
Segmentation fault (core dumped)

Fixed by downgrading CUDA to 10.0 and CuDNN to 7.6.5
Then commented out this lines in utils/rendering.py:
os.environ['PYOPENGL_PLATFORM'] = 'egl'

Configuration:
Pop os 20.04
gtx 1060 6Gb, driver version 460.39
python 3.16.13
tensorflow 1.15.2
ffmpeg version 4.2.4-1ubuntu0.1

I close the os.environ['PYOPENGL_PLATFORM'] = 'egl' and the question disappeared.

I tried 3 days to solve this bug，and I finally know how to solve it.

• First circumstance: I use virtual box(A virtual machine software) to run the demo. I think it is not a good way because it's hard to find where the bug is.
• Second circumstance: I use xshell(A remote machine softward) to run the demo. And I finally solve the problem by following steps：

1. use the address https://pyrender.readthedocs.io/en/latest/install/index.html#installmesa to install osmega
2. os.environ['PYOPENGL_PLATFORM']='egl' should not be commented in rendering.py but commented in visualize_sequence.py
3. Pay attention to the opengl version. Although in the readme you install mesh after pip install -r requirements.txt, you should input pip install -r requirements.txt again after installing mesh. I notice that too high version of opengl will not be supported in remote machine.

I solved the problem by just commenting out the os.environ['PYOPENGL_PLATFORM']='egl' in rendering.py.
