Hi, I found some error at register_segmented.py

100%|██████████████████████████████████████████████████████████████████████████████████████| 42/42 [00:15<00:00, 2.68it/s] Apply post processing 100%|██████████████████████████████████████████████████████████████████████████████████████| 33/33 [00:00<00:00, 58.07it/s]

Traceback (most recent call last):

File "/home/youngwoo/ObjectDatasetTools/register_segmented.py", line 243, in plane_norm = normalize(np.array(plane_equation[:3])) TypeError: 'NoneType' object has no attribute 'getitem'

I got this error after processing. Could you please help me with this error? Thank you!
