Hi
On my Ubuntu, I would reach the arpack wrapper as follows:

However, I'd guess that you deal with a symmetric matrix (Laplacian or
adjacency matrix), so the symmetric

Hello,
I want to use scipy.sparse.linalg.eigen function, but it keeps popping
out error message:
TypeError: 'module' object is not callable
eigen is a module, but it has __call__ method. Why couldn't I call
scipy.sparse.linalg.eigen(...)?
Thanks.

It is very simple code:
import networkx as nx
import scipy.sparse.linalg as linalg
G = nx.Graph()
G.add_star(range(9))
M= nx.to_scipy_sparse_matrix(G)
print linalg.eigen(M)
Thanks.

Here is the command line python:

linalg has no attribute eigen.
Are you able to use scipy.sparse.linalg.eigen?
My working dir is not inside scipy. It is 'C:\\Users\\jankins'.
I am using Python 2.6.2 and the latest version of scipy.

You should post full tracebacks. I don't understand this error,
because before eigen seemed to exist.
You could run the test suite to see if the installation is ok and
sparse is working
