Rendering voxel artefacts, what could be the cause #94

Closed htlpt closed 1 year ago

htlpt commented 1 year ago

I was building on Win11, torch 2.0.1, CUDA 11.8, RTX4090 training the example ngp_fox, seeing voxel artifacts, could it be the platform, the GPU(mix-precision ?), or just torch version.. 20000_001

image I noticed the NaN in the training, possibly FP16 overflow?

low PSNR of course...

It's just the instablity of CUDA on Windows, WSL2 runs just fine...
