I want to ask about running my own pointcloud in S3DIS Fine-tuning #36

Hello, excuse me. I am a novice to 3d semantic segmentation. And it's nice to see your work. I'd like to ask you a few questions. ①I would like to run my own point cloud in the semantic segmentation task of S3DIS Fine-tuning. May I ask whether could I convert my point cloud into the same file structure and format as the Stanford3dDataset_v1.2_Aligned_Version dataset, and then use it as input. In addition, whether the weight of the network (PRETRAIN=PATH_CHECKPOINT) is necessary in the ./scripts/train_stanford3d.sh. ②when I run the code following the README, I encountered problems in ./scripts/train_stanford3d.sh, it reported the following error: image I wonder if you know how to solve it, looking forward to your reply!!

have you got the preprocessed point cloud? can you try to load them by torch.load() to see if there are similar errors?

Thanks！Now everything works successfully. And I want to ask how can I visualize the result of segmentation, because I don't think I saw it. Thanks again for your help.
