Error on running scripts/get_motion_maps.py

[sidsachan]

The error: 0it [00:00, ?it/s] multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "/home/yaoy/anaconda3/envs/AIC2021-T5-CLV/lib/python3.7/multiprocessing/pool.py", line 121, in worker result = (True, func(*args, **kwds)) File "scripts/get_motion_maps.py", line 32, in get_bk_map avg_img = np.mean(np.stack(imgs),0) File "<__array_function__ internals>", line 6, in stack File "/home/yaoy/anaconda3/envs/AIC2021-T5-CLV/lib/python3.7/site-packages/numpy/core/shape_base.py", line 423, in stack raise ValueError('need at least one array to stack') ValueError: need at least one array to stack """

The above exception was the direct cause of the following exception:

Traceback (most recent call last): File "scripts/get_motion_maps.py", line 66, in for imgs in tqdm(pool.imap_unordered(get_bk_map, files)): File "/home/yaoy/anaconda3/envs/AIC2021-T5-CLV/lib/python3.7/site-packages/tqdm/std.py", line 1180, in iter for obj in iterable: File "/home/yaoy/anaconda3/envs/AIC2021-T5-CLV/lib/python3.7/multiprocessing/pool.py", line 748, in next raise value ValueError: need at least one array to stack

In my understanding, this happens when some paths are incorrect. But I cannot figure out what is wrong. Any help is appreciated.

Thanks

have you been able to find solution to this?

@sidsachan @maria-zafar The problem is sometimes it is add an ".ipycheckpoints" to the path just you need to pop it from file list before you get into motion function
