RandAugment in PyTorch (3)

#python #pytorch #randaugment #v2
*Memos:
My post explains RandAugment() about num_ops and fill argument.
My post explains RandAugment() about magnitude and fill argument.
My post explains OxfordIIITPet().
RandAugment() can randomly augment an image as shown below. *It's about num_magnitude_bins and fill argument:
