Here's a good function header given the following:
I wrote the below code

    def _to_absolute_coordinates(normalized_boxes):
        return box_list_ops.to_absolute_coordinates(box_list.BoxList(normalized_boxes), image_shape[1], image_shape[2], check_range=False).get()
    absolute_boxes = tf.map_fn(_to_absolute_coordinates, elems=normalized_boxes, dtype=tf.float32, parallel_iterations=parallel_iterations, back_prop=True)
    return absolute_boxes

What's a good function header?
