Re: [networkx-discuss] 'module' object has no attribute 'all_shotest_paths'

[Dan Schult]

Did you import networkx as nx before running that example code?
>>>import networkx as nx

Somehow its not finding networkx.all_shortest_paths

Maybe you have an old version of NetworkX?
Try
>>> import networkx as nx
>>> print networkx.__version__

The current release is networkx-1.7 http://pypi.python.org/pypi/networkx

Hi Aric,

It say networkx 1.6. How can I upgrade to 1.7?

Should I uninstall 1.6 and then install 1.7?? or is there any mechanism to upgrade directly?

problem solved after upgrading to networkx 1.7

Thanks a lot :)

[lopezd...@gmail.com]

Same with me:

import networkx as nx
G=nx.path_graph(4)
print nx.degree_pearsonr(G)

generates the error: AttributeError: 'module' object has no attribute 'degree_pearsonr'

Hi,all

I have the same problem, and update networkx to the latest 1.7, but it still has the error.

>>> import networkx as nx
>>> print nx.__version__
1.7
>>> G = nx.complete_graph(4)
>>> print nx.all_simple_paths(G, source=0, target=3, cutoff=2)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

AttributeError: 'module' object has no attribute 'all_simple_paths'

thanks for help! 

[Aric Hagberg]

It's called "degree_pearson_correlation_coefficient"

In [1]: import networkx as nx

In [2]: G = nx.house_graph()

In [3]: nx.degree_pearson_correlation_coefficient(G)
Out[3]: -0.33333333333333331
