cugraph.experimental.PropertyGraph.get_vertices#

PropertyGraph.get_vertices(selection=None)[source]#

Return a Series containing the unique vertex IDs contained in both the vertex and edge property data in ascending order. Selection is not yet supported.

Parameters:

selectionPropertySelection, optional: A PropertySelection returned from one or more calls to select_vertices() and/or select_edges()

Returns:

cudf series or pandas series, optional: Contains vertices that match the selection or all

Examples

>>> import cugraph
>>> import cudf
>>> from cugraph.experimental import PropertyGraph
>>> df = cudf.DataFrame(columns=["src", "dst", "some_property"],
...                     data=[(99, 22, "a"),
...                           (98, 34, "b"),
...                           (97, 56, "c"),
...                           (96, 88, "d"),
...                          ])
>>> pG = PropertyGraph()
>>> pG.add_edge_data(df, type_name="etype", vertex_col_names=("src", "dst"))
>>> pG.get_vertices()
