module 'kaolin._C.ops.spc' has no attribute 'points_to_morton_cuda'

[logan-hs]

Hello! I'm trying to get kaolin-wisp working on a GCP Compute Engine VM and everything installs without error, but when I run python3 app/main.py --config configs/ngp_nerf.yaml --multiview-dataset-format standard --mip 0 --dataset-path ../instant-ngp/data/nerf/fox

I get an error: AttributeError: module 'kaolin._C.ops.spc' has no attribute 'points_to_morton_cuda'

I ran dir() on kaolin._C.ops.spc and I did not see points_to_morton_cuda: ['Conv3d_backward', 'Conv3d_forward', 'ConvTranspose3d_backward', 'ConvTranspose3d_forward', '__doc__', '__loader__', '__name__', '__package__', '__spec__', 'generate_points_cuda', 'points_to_octree', 'scan_octrees_cuda', 'to_dense_backward', 'to_dense_forward']

Any idea what might be going on?

Hi @logan-hs , you might have a not-so-recent kaolin version installed, make sure you have the latest master, if yes, you might want to delete kaolin/_C.so and build/ and rebuild kaolin
