Error running example

[Andrew Slaughter]

I am attempting to run the example: http://docs.sympy.org/latest/modules/vector/examples.html#third-product-rule-for-del-operator

Running the following, using sympy (1.0) installed with miniconda in Python 2.7, yields an error. Any help resolving this issue would be appreciated.

CODE:

from sympy.vector import CoordSysCartesian
C = CoordSysCartesian('C')

from sympy import symbols
v1, v2, v3 = symbols('v1 v2 v3 f', type="Function")
v = v1(C.x, C.y, C.z)*C.i + v2(C.x, C.y, C.z)*C.j + v3(C.x, C.y, C.z)*C.z

ERROR:
