[sympy] Finding the Riemann tensor for the surface of a sphere with sympy.diffgeom

I have implemented a SymPy program that can calculate the Riemann curvature tensor for a given curve element. However, I am encountering problems solving for the case when the curve element is the surface of a sphere \begin{align} ds^2 = r^2d\theta^2 + r^2 \sin^2\theta d\phi^2 \end{align} This
