Common Problems

the provided PTX was compiled with an unsupported toolchain

Update your GPU driver or downgrad your spconv/cumm cuda version.

CUDA kernel launch blocks must be positive, but got N= 0

Your coordinates generate nothing with some conv params. Modify your conv params to make sure all input points have at least one output point.

Example:

Conv Params: spatial shape=[8, 200, 200],ksize=3,stride=2,padding=[0, 1, 1],dilation=1 Coordinates:

[[0, 7, 153, 142]]

The convolution in z axis will drop ALL points in z == 7. change the padding-z to solve this problem.
