Bug

Albumentations geometrical transformation (e.g. RandomRotate90) do not work. in Albumentations Yolo box tansformation format is implemented which is different from OBB. As a result, boxes are not transferred correctly.

self.transform = A.Compose(T, bbox_params=A.BboxParams(format="yolo", label_fields=["class_labels"]))

I realize that this is an external library, but I am letting you know in order to introduce information in the documentation that this kind of augmentation will not function properly.
