Bug description:
CUB200 dataset in
torchvision.prototype.datasets
module formed labels using file paths. This resulted in labels being 1-indexed (1-200) instead of 0-indexed (0-199). A related issue from the past was with Flowers102 (torchvision.datasets
module, #5766).This PR simply shifts the labels and makes them zero-indexed for consistency with other datasets.
