Pymanopt

Pymanopt A Python toolbox for optimization on Riemannian manifolds with support for automatic differentiation Riemannian optimization is a powerful framework to tackle smooth nonlinear optimization problems with structural constraints. By encoding structural properties of a problem in the manifold geometry, Riemannian optimization allows for elegant and convenient enforcement of properties such as
