A question about "-1 in Scannet Dataset" #45

Thank you very much for sharing your well organized code. I have a question about ScanNet dataset. I noticed that there is "-1" in the label of the processed ScanNet training set. Is this part of the mask removed during preprocessing? Or does the "-1" label already exist in ScanNet?

Hi, -1 means ignore_label in Pointcept

Thank you for your reply. Does this mean that in ScanNet, those ignored labels do not belong to the 20 categories? Sorry, I'm not particularly familiar with the ScanNet dataset.

Yes.

Yes.

Thank you very mush!
