Cannot run create_label_files.py #32

At line 98 of create_label_files I am getting the following error:

resolve by downgrading to scipy 1.3.3, but now I am getting the following error: test3 is assigned class label 0. 57%|██████████████████████████████████████████████████████████████████▉ | 669/1179 [00:36<00:23, 21.41it/s]Traceback (most recent call last): File "create_label_files.py", line 156, in cnt = max(contours, key=cv2.contourArea) ValueError: max() arg is an empty sequence

TommasoBendinelli commented 4 years ago

I bypass the error by adding the following: try: cnt = max(contours, key=cv2.contourArea) except: pass I suspect that the error is because in some frames there is not object.

Hi, thank you for the comments. Ideally you should keep the object within frame at all time, otherwise it may cause unexpected errors.
