Please refer to https://github.com/traveller59/spconv.

I solved this problem by referring to the following suggestions.

WARNING
Use spconv >= cu114 if possible. cuda 11.4 can compile greatly faster kernel in some situation.

Update Spconv: you MUST UNINSTALL all spconv/cumm/spconv-cuxxx/cumm-cuxxx first, 

use pip list | grep spconv and pip list | grep cumm to check all installed package. 

then use pip to install new spconv.

I use pip list | grep cumm and find two version cumm installed in the virtual environment. I uninstall the dismatched version and the error disappears.
