tf.contrib.copy_graph.copy_op_to_graph

Returns a copy of an operation from another Graph under a specified scope.

tf.contrib.copy_graph.copy_op_to_graph(
    org_instance, to_graph, variables, scope=''
)

Given an Operation org_instance from one Graph, initializes and returns a copy of it from another Graph, under the specified scope (default "").

The copying is done recursively, so any Operation whose output is required to evaluate the org_instance, is also copied (unless already done).

Since Variable instances are copied separately, those required to evaluate org_instance must be provided as input.

Args
org_instance	An Operation from some Graph. Could be a Placeholder as well.
to_graph	The Graph to copy org_instance to.
variables	An iterable of Variable instances to copy org_instance to.
scope	A scope for the new Variable (default "").

Returns
The copied Operation from to_graph.

Raises
TypeError	If org_instance is not an Operation or Tensor.
