OxfordIIITPetaX `Oxford-IIIT Pet Dataset `_.
Args:
root (str or ``pathlib.Path``): Root directory of the dataset.
split (string, optional): The dataset split, supports ``"trainval"`` (default) or ``"test"``.
target_types (string, sequence of strings, optional): Types of target to use. Can be ``category`` (default) or
``segmentation``. Can also be a list to output a tuple with all specified target types. The types represent:
- ``category`` (int): Label for one of the 37 pet categories.
- ``binary-category`` (int): Binary label for cat or dog.
- ``segmentation`` (PIL image): Segmentation trimap of the image.
If empty, ``None`` will be returned as target.
transform (callable, optional): A function/transform that takes in a PIL image and returns a transformed
version. E.g, ``transforms.RandomCrop``.
target_transform (callable, optional): A function/transform that takes in the target and transforms it.
transforms (callable, optional): A function/transform that takes input sample
and its target as entry and returns a transformed version.
download (bool, optional): If True, downloads the dataset from the internet and puts it into
``root/oxford-iiit-pet``. If dataset is already downloaded, it is not downloaded again.
