on a JuliaBox session notebook running an 0.4.2 kernel, your code evaluates to:
In [3]: sp.gmres(np.eye(5,5),np.zeros(5)) /home/juser/.local/lib/python2.7/site-packages/numpy/core/fromnumeric.py:2499: VisibleDeprecationWarning: `rank` is deprecated; use the `ndim` attribute or function instead. To find the rank of a matrix see `numpy.linalg.matrix_rank`. VisibleDeprecationWarning) Out[3]: ([0.0,0.0,0.0,0.0,0.0],0)
