    Args:
        root (string): Root directory where images are downloaded to.
        split (string): One of {'train', 'valid', 'test', 'all'}.
            Accordingly dataset is selected.
        target_type (string or list, optional): Type of target to use, ``attr``, ``identity``, ``bbox``,
            or ``landmarks``. Can also be a list to output a tuple with all specified target types.
            The targets represent:

                - ``attr`` (Tensor shape=(40,) dtype=int): binary (0, 1) labels for attributes
                - ``identity`` (int): label for each person (data points with the same identity are the same person)
                - ``bbox`` (Tensor shape=(4,) dtype=int): bounding box (x, y, width, height)
                - ``landmarks`` (Tensor shape=(10,) dtype=int): landmark points (lefteye_x, lefteye_y, righteye_x,
                  righteye_y, nose_x, nose_y, leftmouth_x, leftmouth_y, rightmouth_x, rightmouth_y)

            Defaults to ``attr``. If empty, ``None`` will be returned as target.

        transform (callable, optional): A function/transform that  takes in an PIL image
            and returns a transformed version. E.g, ``transforms.PILToTensor``
        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.
