RandomRotation transform

Good Morning,
I would like to know if there is a way of knowing what random angle is used to perform transformation

You have to define the angle by passing the degrees to torchvision.transforms.RandomRotation.
From the docs:

degrees ( sequence or float or int ) – Range of degrees to select from. If degrees is a number instead of sequence like (min, max), the range of degrees will be (-degrees, +degrees).
