Hello, thank you very much for your work.
I tried to replace the semanticKITTI dataset with my own dataset, but I encountered the following error during training. I have tried many methods, but I still couldn't solve this issue. Do you know how to fix it? Thank you very much for your help.

Hi @xiaosa269 , are you willing to share more information about the modification and dataset? From the info above, I cannot locate the issue.
