Question about grad contiguous #9

I am wondering why the segmentation methods require spconv lib to have grad contiguous meanwhile some detection method based on spconv does not require this. Do you know what is causing problems?.

Sry that I don't know the exact reason. If grad is not contiguous, the first stage converges well while the second stage fails. I guess the code written with CUDA (clustering and instance voxelization) makes the difference.
