@QingyongHu I'm trying to run ''data_prepare_s3dis.py'' file and it's showing me this error:

''' randla-net\data\S3DIS\Stanford3dDataset_v1.2_Aligned_Version/Area_1/conferenceRoom_1/Annotations Traceback (most recent call last): File "data_prepare_s3dis.py", line 80, in convert_pc2ply(annotation_path, join(original_pc_folder, out_file_name)) File "data_prepare_s3dis.py", line 47, in convert_pc2ply pc_label = np.concatenate(data_list, 0) File "<array_function internals>", line 6, in concatenate ValueError: need at least one array to concatenate ''' Any help please?!

Hi @youssef962, in data_prepare_s3dis.py edit data path or change to absolute path of dataset.
