eigen is both a function and a module. Normally the function shadows the module

>python
Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy.sparse.linalg.eigen
>>> scipy.sparse.linalg.eigen
<function eigen at 0x01541AB0>

I'm not able to import the eigen module, so there is either something
different with python 2.6 or networkx is doing some magic ?

Can you try without networkx, try linalg.eigen.eigen ?

Does
>>> scipy.sparse.linalg.eigen

show the module or the function?

Josef

PS: I don't like functions shadowing a module
