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.
