Scipy's Optimize Curve Fit Limits

Question

Is there any way I can provide limits for the Scipy\'s Optimize Curve Fit?

My example:

    def optimized_formula(x, m_1, m_2, y_1, y_2, ratio_2):
            


        

Answer 1

Try the lmfit module (http://lmfit.github.io/lmfit-py/). It adds a way to fix or set bounds on parameters for many of the optimization routines in scipy.optimize, including least-squares, and provides many tools to make fitting easier.
