dilation -- The stride between elements within a sliding
        window, must be > 0.


ceil_mode -- If "True", will use ceil instead of floor
    to compute the output shape. This ensures that every element
    in the input tensor is covered by a sliding window.


return_indices -- If "True", will return the argmax along
    with the max values. Useful for
    "torch.nn.functional.max_unpool2d" later
