10 months ago There maybe some files like ._celing_1.txt in your dataset, in preprocess.py, use if ((room_name != ".DS_Store" and not room_name.startswith(".") ) and ".txt" not in room_name)]
Hi,here is a problem! multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "/home/jsjlab/anaconda3/envs/pcr/lib/python3.8/multiprocessing/pool.py", line 125, in worker result = (True, func(*args, **kwds)) File "/home/jsjlab/anaconda3/envs/pcr/lib/python3.8/multiprocessing/pool.py", line 51, in starmapstar return list(itertools.starmap(args[0], args[1])) File "pcr/datasets/preprocessing/s3dis/preprocess_s3dis.py", line 60, in parse_room room_coords = np.ascontiguousarray(np.vstack(room_coords)) File "<__array_function__ internals>", line 5, in vstack File "/home/jsjlab/anaconda3/envs/pcr/lib/python3.8/site-packages/numpy/core/shape_base.py", line 283, in vstack return _nx.concatenate(arrs, 0) File "<__array_function__ internals>", line 5, in concatenate ValueError: need at least one array to concatenate """
The above exception was the direct cause of the following exception:
Traceback (most recent call last): File "pcr/datasets/preprocessing/s3dis/preprocess_s3dis.py", line 116, in
main_process()
File "pcr/datasets/preprocessing/s3dis/preprocess_s3dis.py", line 109, in main_process

Can you help me?Thank you!
