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

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

#### Args:

• 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.
• 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_outputs: a util.ControlOutputs instance or None. If not None, it will be used while walking the graph forward.

#### Returns:

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

#### Raises:

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