ber 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={tv_tensors.Image: 127, tv_tensors.Mask: 0}`` where ``Image`` will be filled with 127 and
            ``Mask`` will be filled with 0.
