EGL Error when caling the render function

[Bensong0506]

File "/shared/scannetpp/common/render.py", line 47, in main render_engine = renderpy.Render() RuntimeError: EGL error at eglInitializewith error code: 12296

Hi I managed to install and build the renderpy in the conda environment, but I got this error and I had no idea how to solve it.

Hi! I didn't have this issues before. Could you share a bit about your environment? like operating system, version, nvidia driver version etc.

Did you have the opengl package properly installed? is it installed in the conda env or in the system using apt install? (like libgl1-mesa-dev libglu1-mesa-dev)

Some people also have this error when EGL init but fixed by upgrading the nvidia driver

hello, sir. I met the OpenGL.error.GLError: err=12289. some information about my environment are as follows.

I have the same issue.

I have the same issue.

i met this problem when i tried to run the VIBE project. my error is 12289 while yours is 12296. maybe the pyrender or the EGL is the reason. when i tried VIBE in the COLAB, the problem disappeared.

Thanks for reporting. I will try different machines and environments and see if I can reproduce the issue but it might take a while.

At the meantime, a quick solution will be using other tools to do the rendering. I assume the main usage here is to render depth for ScanNet++ images. An alternative we had tried is to use pytorch3d MeshRasterizer. Reference that render semantic labels into 2D: https://github.com/scannetpp/scannetpp/blob/main/semantic/prep/rasterize_semantics_2d.py you should be able to read the z-buffer the get the depth map.

Is there any better solution for this error? I have also encountered this error with Ubuntu22.04 My device infomation:

I met this problem too. Are there any possible solutions?

I also have EGL error：

['Render', 'doc', 'file', 'loader', 'name', 'package', 'spec', 'version'] Init EGL Detected 4 devices Using device 0 Using EGL version 1.5 OpenGL version: 4.6.0 NVIDIA 550.107.02 EGL version: 1.5 Bus error (core dumped)

@junyuan-fang Have you fixed this problem?

[junyuan-fang]

@miaolin968 Nope. Have you?

[miaolin968]

@junyuan-fang Nope. And my problem is: "Detected 0 devices" means EGL can't detecte my GPU

I also meet the similar problem, is there any solution?
