Dear author: thanks for your wonderful work!!! my ubuntu is 20.04 and i follow the "spconv" , which say i can use "pip install spconv-cu113" to install spconv, and after this, i run your "python setup.py develop " and there is no wrong. But when i run the train.py, it raise wrong: AttributeError: module 'spconv' has no attribute 'SparseConv3d', this looks like "python setup.py develop" is actually failed (T T). Am i guess right? could you help me? look forward your response!!!!!!~~~~~
