not_implemented_for(*graph_types)

Notes

Multiple types are joined logically with "and". For "or" use multiple @not_implemented_for() lines.

Parameters

graph_types : container of strings

Entries must be one of "directed", "undirected", "multigraph", or "graph".

Raises

NetworkXNotImplemented
If any of the packages cannot be imported

Returns

_require : function

The decorated function.

Decorator to mark algorithms as not implemented

Examples

@not_implemented_for("directed") def sp_function(G): pass

# rule out MultiDiGraph @not_implemented_for("directed","multigraph") def sp_np_function(G): pass

# rule out all except DiGraph @not_implemented_for("undirected") @not_implemented_for("multigraph") def sp_np_function(G): pass

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
