Ahh, that makes sense. It is the sympy.python thing that causes the
problem. This hack seems to work fix the issue in the notebook:
import sympy
sympy.sage_python = sympy.python
del sympy.python
from sympy import *
But any code in sympy that uses sympy.python will now fail. Really
this is a bug in sage though.
