Real time renderer

Hi, When I used the SIBR real time viewer, it gives me this warning.

Also when I switch rendering type to Ellipsoids, the whole system seems to stop and I cannot move around the scene. Is this also related to the former warning ?

The command I used is ./<SIBR install dir>/bin/SIBR_gaussianViewer_app -m <path to trained model> --device 0

PyTorch: 1.12.1
CUDA: 11.7 
OpenGL: 4.5 (Mesa 21.2.6)
Device: NVIDIA A6000 (48G)

1. try --device 1 on your system if it have more then one GPU. Setting default GPU can help.
2. Check what CUDA is dedicated to your GPU and reinstal it.

Hi, I tried --device 1 but it gives me the same warning. And I guess CUDA - GPU compatibility is fine since I have been using the same version on other conda envs and worked fine.

Try search for another copy of viewier at (gs-catalog) \viewer\bin\SIBR_gaussianViewer_app.exe It is already compiled and can be different if you compiled your own.

Hi, l met the same issue. May I ask what is your conda envs configuration that worked fine for Ellipsoids Rendering? By the way, are you using Ubuntu 22 or Ubuntu 20?

hi @jh27kim, any news on this? I am using Ubuntu 22 and met the same CUDA/OpenGL interop issue.

Does it happen on Windows as well?

Do you have a system with more than GPU? Is the non-NVIDIA GPU the one that is connected to the monitor?

I am running it on a laptop equipped with Nvidia GTX 1650 Ti. This is the output of the command:

I think the interesting lines are the ones related to MESA and libGL errors

Ok thanks. so does it actually run at all, with the non-interop mode? Because GTX 1650 is definitely older than what we aim to support.

Hi, I also met this problem, have you solved it?

You can try the following command:

sudo apt-get install nvidia-prime
sudo prime-select nvidia
