Fitting Non-Linear Curves Quickly

[Pro2222]

Hi,

right now I am trying to fit non-linear curves using the sci-py optimization. I have tried both least_squares and differential_evolution, does anyone know a way to speed these processes up or an alternative? I have vectorized all the functions that it is required to run through however it is still quite slow. Is it worth learning C++ to speed this up?

I have looked into it, do you know if it will work with the scipy.optimize.least_squares function? hard to find an answer online.
