Comment(by pv):

 Here's a crasher with an explicit initial vector:
 {{{
 import numpy as np
 from scipy.sparse.linalg import eigs

 N = 6
 k = 2

 np.random.seed(2301)
 A = np.random.random((N,N))

 v0 = np.array([-0.71063568258907849895, -0.83185111795729227424,
                -0.34365925382227402451, 0.46122533684552280420,
                -0.58001341115969040629, -0.78844877570084292984e-01])

 evals, evecs = eigs(A, k, v0=v0)
 }}}
