tf.contrib.graph_editor.get_backward_walk_ops()

tf.contrib.graph_editor.get_backward_walk_ops(seed_ops, inclusive=True, within_ops=None, stop_at_ts=(), control_inputs=False)

Do a backward graph walk and return all the visited ops.

Args:

• seed_ops: an iterable of operations from which the backward graph walk starts. If a list of tensors is given instead, the seed_ops are set to be the generators of those tensors.
• inclusive: if True the given seed_ops are also part of the resulting set.
• within_ops: an iterable of tf.Operation whithin which the search is restricted. If within_ops is None, the search is performed within the whole graph.
• stop_at_ts: an iterable of tensors at which the graph walk stops.
• control_inputs: if True, control inputs will be used while moving backward.

Returns:

A Python set of all the tf.Operation behind seed_ops.

Raises:

• TypeError: if seed_ops or within_ops cannot be converted to a list of tf.Operation.
