SparseConvTensor attribute is missing for spconv at runtime

[choubaoy]

Thank you very much for sharing this project. Here is a problem that I need to ask you. I debugged it myself and didn't solve it. Do you know the cause of this error?The specific error message is"AttributeError: module 'spconv' has no attribute 'SparseConvTensor'"

Do you use the newest SPConv? The SPConv seems to update to 2.0 versions and changes some API.
Please use the SPConv proposed in PointGroup.

Thank you for your answer. I have improved this question according to your suggestions.Here is another question to ask.The results of the test code only have exponential results. Is there any way to visualize the results?Thank you again for your code sharing, and we look forward to your answer to the visualization of the results.
