Return the union of a forward and a backward walk.

Args:

  • forward_seed_ops: an iterable of operations from which the forward graph walk starts. If a list of tensors is given instead, the seed_ops are set to be the consumers of those tensors.
  • backward_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.
  • forward_inclusive: if True the given forward_seed_ops are also part of the resulting set.
  • backward_inclusive: if True the given backward_seed_ops are also part of the resulting set.
  • within_ops: restrict the search within those operations. If within_ops is None, the search is done 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.
  • control_inputs: A boolean indicating whether control inputs are enabled.
  • control_outputs: An instance of util.ControlOutputs or None. If not None, control outputs are enabled.
  • control_ios: An instance of util.ControlOutputs or None. If not None, both control inputs and control outputs are enabled. This is equivalent to set control_inputs to True and control_outputs to the util.ControlOutputs instance.

Returns:

A Python set of all the tf.Operation in the union of a forward and a backward walk.

Raises:

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