graphscope.framework.dag_utils.add_labels_to_graph¶

graphscope.framework.dag_utils.add_labels_to_graph(graph, loader_op)[source]¶

Add new labels to existed graph.

Parameters:

graph (Graph) – A graph instance. May not be fully loaded. i.e. it’s in a building procedure.
loader_op (graphscope.framework.operation.Operation) – Operation of loader.

Raises:

NotImplementedError – When encountered not supported graph type.

Returns:

The operation.

Notes

Since we don’t want to trigger the loading, we must not use any api that can trigger the loading process implicitly.
