radii > 0 - CUDA error illegal access memory

Hi !

Currently trying to give a try to your method on a custom scene I have but I'm facing quite a disturbing and strange issue. Training starts well, but at some points, I got some CUDA-kernel error I cannot get.

I highly suspect an issue related to the gaussians.compute_3D_filter method (https://github.com/autonomousvision/mip-splatting/blob/746a17c9a906be256ed85b8fe18632f5d53e832d/train.py#L164C1-L165C1) but I don't manage to investigate in a deeper way the error.

I've found some similar issue in the original GS repo (here: graphdeco-inria/gaussian-splatting#41 (comment)), made the corresponding changes by rebuilding the diff-gaussian-rasterizer submodule, but I still get the error.

Here is the log stack I get.

Do you have any clues / insights on what's happening and why ?

Thanks a lot for your time, your work,

Best,

Gaétan.

Hi, not sure what’s wrong. Do you find a solution in the end?

I meet the similar problem. Have you fixed it up?

I fixed the problem by using a new WSL machine with cuda 118
