Sparse Adam cuda error

[ricshaw]

I'm getting a cuda error when using diff_gaussian_rasterization with sparse adam optimizer with cuda 12.
Without sparse adam optimizer it works just fine....

CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with TORCH_USE_CUDA_DSA to enable device-side assertions.
