.. note::
                In torchscript mode padding as single int is not supported, use a sequence of
                length 1: ``[padding, ]``.
        fill (number or tuple or dict, optional): Pixel fill value used when the  ``padding_mode`` is constant.
            Default is 0. If a tuple of length 3, it is used to fill R, G, B channels respectively.
            Fill value can be also a dictionary mapping data type to the fill value, e.g.
            ``fill={datapoints.Image: 127, datapoints.Mask: 0}`` where ``Image`` will be filled with 127 and
            ``Mask`` will be filled with 0.
        padding_mode (str, optional): Type of padding. Should be: constant, edge, reflect or symmetric.
            Default is "constant".

            - constant: pads with a constant value, this value is specified with fill

            - edge: pads with the last value at the edge of the image.

            - reflect: pads with reflection of image without repeating the last value on the edge.
              For example, padding [1, 2, 3, 4] with 2 elements on both sides in reflect mode
              will result in [3, 2, 1, 2, 3, 4, 3, 2]

            - symmetric: pads with reflection of image repeating the last value on the edge.
              For example, padding [1, 2, 3, 4] with 2 elements on both sides in symmetric mode
              will result in [2, 1, 1, 2, 3, 4, 4, 3]
