Issue with step 6

[KatharinaSchmidt]

Hello,

i tried to run step 6 with python create_label_files.py all and generate labels for the example class "timer".
But I get the following error message:

timer is assigned class label 0.
0%| | 0/600 [00:00<?, ?it/s]
Traceback (most recent call last):
File "create_label_files.py", line 154, in
_, contours, _ = cv2.findContours(thresh.copy(), cv2.RETR_EXTERNAL,
ValueError: not enough values to unpack (expected 3, got 2)

And my triangular mesh (generated with register_segmented.py) semms to look a little bit weird:

Even if I process the registered pointcloud manually (as described in step 5) I get that error message above.

Can you please give me an advice how to solve this?
Thanks
