Anyone met the similar error?

I met the same error... waiting for an answer

Hey man which version of spconv did you use? I use spconv2.0+, then this error appeared; I also want to try spconv1.2.1 as they recommended, but I failed to compile that. Did you meet the same situation? 获取 Outlook for iOS<https://aka.ms/o0ukef>

I encountered similar problem and solved it by "python demo_folder.py --demo-folder /mnt/data/datasets/kitti/sequences/00/velodyne/ --save-folder ./results/". Good luck.

Does anyone else still has this problem?
