    Args:
        root (str or ``pathlib.Path``): Root directory of the VOC Dataset.
        year (string, optional): The dataset year, supports years ``"2007"`` to ``"2012"``.
        image_set (string, optional): Select the image_set to use, ``"train"``, ``"trainval"`` or ``"val"``. If
            ``year=="2007"``, can also be ``"test"``.
        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.
        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
