the function of random_perspective in dataloaders.py causes labels4 to become empty

[Tristesse-stk]

When I run the train.py, the labels4 and segments4 become empty after the function of random_perspective in dataloaders.py.

@Tristesse-stk! Well, Can you share the img4, labels4 and segments4 values with print command, so that I can understand the issue in more better way.

[Tristesse-stk]

@RizwanMunawar Ok.

@RizwanMunawar Maybe it will more convenient for you if I give my datasets including annotations to you?
This is my first time to do instance segmentation project, maybe there is something wrong in my annotations.

[RizwanMunawar]

@Tristesse-stk. Well! did you used Roboflow for data labeling?
Sure, you can reach me through LinkedIn from mentioned link below, and we can discuss.
