ValueError: Expected more than 1 value per channel when training, got input size torch.Size([1, 12, 1])**
Upon reviewing the sizes of the tensors involved: (points_features) shape: torch.Size([1, 9]) (points_neighbor) shape: torch.Size([1, 9]) (points_features) shape: torch.Size([1, 9]) (pointnet1_in_fea) shape: torch.Size([1, 1, 6]) one can see that after running the function roicrop3d_gpu, no inner ROI point is retrieve from the pseudo point cloud which throws an error when forwarding batch layer.
I do not how to solve this issue. I have been debugging and trying different things for weeks. Thank you in advance!
