Saosen Kuang

Sir, I meet the problem " AttributeError: module 'spconv' has no attribute 'SubMConv3d' ", And I tried " pip install spconv-cu111 ", but it did not work.....I feel like knowing...

Thank you !! I was trapped by this problem for a long time. I tested the code on the colab, meeting many issues（file path & invalid versions of different codebase）........
