mlx_graphs.utils.transformations.to_undirected

mlx_graphs.utils.transformations.to_undirected(edge_index: mlx.core.array, edge_features=None) → mlx.core.array

mlx_graphs.utils.transformations.to_undirected(edge_index: mlx.core.array, edge_features: mlx.core.array) → tuple[mlx.core.array, mlx.core.array]

Converts a graph given as edge_index and, optionally, edge_features to an undirected one.

Parameters:

• edge_index (array) – The edge index of the graph.

• edge_features (Optional[array]) – Edge features associated with each edge.

Return type:

Union[array, tuple[array, array]]

Returns:

The undirected edge_index (and edge_features)
