Missing point cloud data for some scenes.
Hi, I am trying to fine-tune the SpatialLM model using your preprocessed Structured3D-SpatialLM dataset, but the code throws the following error: next_batch = next(dataloader_iter)

ValueError: zero-size array to reduction operation minimum which has no identity”，I checked the pcd folder and found that point cloud files such as pcd/scene_01017.ply and pcd/scene_01018.ply are missing, even though they exist in structured3d_train.json. Could you provide the missing data?
Thank you for noting the issue, I will check the missing data, and update the dataset in a day or two.
