I've been trying to use sagemath for a derivation in general relativity. For a particular step I need to calculate the riemann tensor of a perturbation metric (This metric has no particular form) and the cell did not execute for even after 16 hours of run time. Here's the snippet of my code. can someone help me in defining a metric in some other way, probably indicial notation or something else so that the process can speed up?

here's a minimal code:
h=M.metric('h') for i in range(4): for j in range(4): h[i, j] = function(f'h{i}{j}')(t, x, y, z) h[i, j] = h[j, i]
h[:] riemann=h.riemann() riemann.display()
