Re: [networkx-discuss] max_clique() function error: networkx.algorithms has no attribute 'approximation'

[Daniel Schult]

The first thing to check is the networkx version (and python version too).  The docs are for the latest version but you may be accessing an older version.

I want to use max_clique() function on a graph G

http://networkx.github.io/documentation/latest/_modules/networkx/algorithms/approximation/clique.html#max_clique

I called

networkx.algorithms.approximation.clique.max_clique(G) and get  an error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'approximation'

what is wrong with it?

thanks!

the version is:

Python 2.7.3
networkx: 1.8.1

[Aric Hagberg]

It should work with that version:

In [1]: import networkx as nx

In [2]: G = nx.complete_graph(4)

In [3]: from networkx.algorithms.approximation import clique

In [4]: clique.max_clique(G)
Out[4]: set([0, 1, 2, 3])
