    Args:
        root (string): Root directory of the ImageNet Dataset.
        split (string, optional): The dataset split, supports ``train``, or ``val``.
        transform (callable, optional): A function/transform that  takes in an 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.
        loader (callable, optional): A function to load an image given its path.

     Attributes:
        classes (list): List of the class name tuples.
        class_to_idx (dict): Dict with items (class_name, class_index).
