Function Usage

Replaces the subgraph described by boundary with replacement. This is a static method.

Prototype

@staticmethod
replace(boundary: SubgraphBoundary, replacement: Graph) -> int

Parameters

Parameter	Input/Output	Description
boundary	Input	Subgraph boundary, which is of the SubgraphBoundary type. It describes the input or output of the subgraph to be replaced.
replacement	Input	Replacement graph, which is of the ge.graph.Graph type.

Returns

Type	Description
int	The integer form of the C++ Status. In case of failure, check the logs for information about boundary integrity and index alignment.

Restrictions

The replacement must be a non-empty graph wrapper. The graph will be copied on the C++ side, but you must still follow GE's ownership rules for Python graph objects.

Example

from ge.passes import SubgraphBoundary, SubgraphInput, SubgraphOutput, SubgraphRewriter

# n0 and out_node are existing nodes in the main graph, and replacement_graph is the constructed replacement graph.
b = SubgraphBoundary()
b.add_input(0, SubgraphInput([(n0, 0), (n0, 1)]))
b.add_output(0, SubgraphOutput(out_node, 0))
ret = SubgraphRewriter.replace(b, replacement_graph)
