Rasterizer Outputs Only Zeros

[AmineElhafsi]

Hello,

I'm trying to build on your Gaussian-SLAM repository using this rasterizer however I'm finding that when I use this rasterizer, the render output is consistently an array of zeros for both the rendered color and depth. Have you ran into anything like this?

I've been trying to debug with the Replica dataset, and I'm pretty sure I'm handling the color/depth and pose information correctly. I just wanted to check if to see if I could get any clue as to what could be going on.

Thanks!

As a related comment, I also frequently get the following error as well:

RuntimeError: CUDA error: an illegal memory access was encountered
Compile with TORCH_USE_CUDA_DSA to enable device-side assertions.

I haven't been able to identify the source of this yet either, but I suspect they may be related.

Hey there,

I didn't encounter it myself, just tested and it seems like working. I tested it on RTX3090. Might it be happening because of CUDA installation?
