Args:
    root (str or ``pathlib.Path``): Root directory of dataset where tarball
        ``SBUCaptionedPhotoDataset.tar.gz`` exists.
    transform (callable, optional): A function/transform that takes in a PIL image or torch.Tensor, depends on the given loader,
        and returns a transformed version. E.g, ``transforms.RandomCrop``
    target_transform (callable, optional): A function/transform that takes in the
        target and transforms it.
    download (bool, optional): If True, downloads the dataset from the internet and
        puts it in root directory. If dataset is already downloaded, it is not
        downloaded again.
    loader (callable, optional): A function to load an image given its path.
        By default, it uses PIL as its image loader, but users could also pass in
        ``torchvision.io.decode_image`` for decoding image data into tensors directly.
