tf.contrib.graph_editor.get_backward_walk_ops

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

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

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 within which the search is restricted. If within_ops is None, the search is performed within the whole graph.
within_ops_fn	if provided, a function on ops that should return True iff the op is within the graph traversal. This can be used along within_ops, in which case an op is within if it is also in within_ops.
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.
