…edge_data, exclude internal `_WEIGHT_` column from `edge_property_names`, added `num_vertices_with_properties` attr (#2419) Add options to `extract_subgraph()` to bypass renumbering and adding edge_data, exclude internal `_WEIGHT_` column from `edge_property_names`. Also added a new attribute `num_vertices_with_properties` which returns the number of vertices with properties, which is different than the number of vertices, since vertices can be added via `add_edge_data()`. This is needed for GNN use cases which need to know how many verts have properties which can be accessed (this corresponds to the number of rows in the internal vertex prop data table). Added unit tests to verify new `extract_subgraph()` options work, the new `num_vertices_with_properties` attribute, and `_WEIGHT_` columns names aren't included, for both SG and MG versions. closes #2418 closes #2410 Authors: - Rick Ratzel (https://github.com/rlratzel) Approvers: - Alex Barghi (https://github.com/alexbarghi-nv) - Erik Welch (https://github.com/eriknw) - Brad Rees (https://github.com/BradReesWork) URL: #2419

PropertyGraph.extract_subgraph()should provide options to bypass renumbering and adding edge_data. Some use cases benefit from the memory savings of not adding the unneededsubgraph.edge_data, and also require vertices that are not renumbered.The text was updated successfully, but these errors were encountered:
