WebMar 2, 2024 · These errors can often be eliminated by passing appropriate initial guesses for each parameter through the p0 argument (which it looks like you're already doing), and/or by passing additional kwargs through to scipy.optimize.leastsq (), like ftol and maxfev which set the fit tolerance and max number of iterations. WebNov 13, 2014 · Now, we are ready to perform the fit: popt, pcov = curve_fit(func, x, y, p0=guess) fit = func(x, *popt) To see how well we did, let's plot the actual y values (solid … chinese fake gold
