See the guide: Graph Editor (contrib) > Module: select

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 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.
