Hi,
I think you are getting trouble because you are mixing two namespaces.
If you separate both packages,
for example like this:
import sympy as sp
import scipy as sc
you can choose which namespace you want to pick a function from by
saying:
f=sp.Function("f")
x=sp.Symbol('x')
eqn=sp.diff(f(x),x)
By the way, your example would work, just by changing the order of your
imports, but this would be not a clean way to solve the problem.
Cheers,
Tobi
