May I ask if spnn. conv3d in torch sparse is a submanifold sparse convolution or a regular sparse convolution? How to distinguish like spconv.SubMConv3d and spconv.SparseConv3d in spconv?

Expected Behavior

Environment

- GCC:
- NVCC:
- PyTorch:
- PyTorch CUDA:

We support both submanifold and regular sparse convolution in spnn.conv3d. Just change the stride parameter to run the two types of convolution.
