cugraph.structure.NumberMap.to_internal_vertex_id

NumberMap.to_internal_vertex_id(df, col_names=None)

Given a collection of external vertex ids, return the internal vertex ids

Parameters:

df: cudf.DataFrame, cudf.Series, dask_cudf.DataFrame, dask_cudf.Series

Contains a list of external vertex identifiers that will be converted into internal vertex identifiers

col_names: (optional) list of strings

This list of 1 or more strings contain the names of the columns that uniquely identify an external vertex identifier

Returns:

vertex_idscudf.Series or dask_cudf.Series

The vertex identifiers. Note that to_internal_vertex_id does not guarantee order or partitioning (in the case of dask_cudf) of vertex ids. If order matters use add_internal_vertex_id
