      This function used to be needed to support tf 1.4 and early, but support for tf 1.4 and earlier is now dropped.

      :param input_tensor: The tensor to reduce. Should have numeric type.
      :param axis: The dimensions to reduce. If None (the default),
              reduces all dimensions. Must be in the range
