Using yolov5_obb for oriented number plates

[RishabhSheoran]

Hi! I want to use yolov5_obb for rotated/oriented number plates. In my dataset, I do not have the 'difficulty' label. Any possible way to handle it and not hamper the performance of the model? How does the 'difficulty' level affect the performance of the model other than the fact that if difficulty=2, the example is ignored?
