Function make_list_of_op

Convert ops to a list of `tf.Operation`. Args: tops: can be an iterable of `tf.Operation`, a `tf.Graph` or a single operation. check_graph: if `True` check if all the operations belong to the same graph. allow_graph: if `False` a `tf.Graph` cannot be converted. ignore_ts: if
