Ah, thanks. I was confused since
In [2]: from scipy.splinalg.eigen import arpack
In [3]: dir(arpack)
Out[3]:
['__all___',
'__builtins__',
'__doc__',
'__docformat__',
'__file__',
'__name__',
'_arpack',
'_ndigits',
'_type_conv',
'aslinearoperator',
'eigen',
'eigen_symmetric',
'np',
'warnings']
yielded a blank. Perhaps I should have looked further :)
