classmethod PropertyGraph.is_multigraph(df)[source]#

Parameters:

dfdataframe: Containing edge data

Returns:

bool: True if df has one or more edges with the same source, destination pair

Examples

>>> import cugraph
>>> import cudf
>>> from cugraph.experimental import PropertyGraph
>>> pG = PropertyGraph()
>>> df = cudf.DataFrame(columns=["src", "dst", "edge_ids", "some_property"],
...                     data=[(99, 22, 3, "a"),
...                           (98, 34, 5, "b"),
...                           (98, 34, 7, "c"),
...                           (96, 88, 11, "d"),
...                          ])
>>> pG.add_edge_data(df, type_name="etype",
...                  vertex_col_names=("src", "dst"),
...                  edge_id_col_name="edge_ids")
>>> pG.is_multigraph(pG.get_edge_data())
True
