importing and optimizing a mesh made from pygmsh

[vaasuanandatheertha]

Could someone throw some light on optimising pygmsh mesh output using optimesh. Tried many ways, some errors thrown are:

optimesh.optimize(mesh, "laplace", 1.0e-2, 100, False), ERROR: 'Mesh' object has no attribute 'edges'
optimesh.laplace.fixed_point(mesh.points, mesh.cells[1], 1.0e-5, 50), ERROR: module 'optimesh.laplace' has no attribute 'fixed_point' as in the example, EXAMPLE FROM REPO.

Mesh is primarily obtained as:
mesh = geometry.generate_mesh(dim = dimensionality, order = Mesh_Order, algorithm = Meshing_Algorithm)

Should I be preparing pygmsh mesh before taking it into optimesh?
