My actual error message is: 
File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 311, in __init__
     self._spline = splmake(x,oriented_y,order=order) 
  File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 809, in splmake
     coefs = func(xk, yk, order, conds, B) 
  File "/lustre/work/apps/python-2.7.1/lib/python2.7/site-packages/scipy/interpolate/interpolate.py", line 530, in _find_smoothest
