thanks for all. this issue as follows, make me do not know how to solve it. please help me. (py37) C:\Users\17342>python G:\multi-obj\data\CNN\pvcnn-master\pvcnn-master\train.py configs/s3dis/pvcnn/area5/c1.py --devices 0,1 ==> loading configs from ['configs/s3dis/pvcnn/area5/c1.py']...

About these two lines of code: ``` norm_coords = torch.clamp(norm_coords * self.r, 0, self.r - 1) vox_coords = torch.round(norm_coords).to(torch.int32) ``` The range of norm_coords should be [0,1], so if self.r...

voxel_features, voxel_coords = self.voxelization(features, coords) right now I am using CUDA 11.3 and Pytorch 1.12 and I have the exact issue, without giving any error, the code runs and produces...

Hello, I am trying to predict your S3dis_model on my custom data without any labels my data is like xyz_room.npy and I was using your prepare_data.py for the preparation of...
