Yes. I am using scipy.sparse.linalg.eigen.arpack.

The exact output is:

/usr/local/lib/python2.6/dist-packages/scipy/sparse/linalg/eigen/arpack/_arpack.so

In fact, the matrix is from a directed graph with about 18,000 nodes and 
41,000 edges. Actually, this matrix is the smallest one I used.

Now I switch to use numpy.linalg.eigvals, but it is slower than 
scipy.sparse.linalg.eigen.arpack module.

Thanks.
