Gaussian fit for Python

Question

I\'m trying to fit a Gaussian for my data (which is already a rough gaussian). I\'ve already taken the advice of those here and tried curve_fit and leasts

Answer 1

You get a horizontal straight line because it did not converge.

Better convergence is attained if the first parameter of the fitting (p0) is put as max(y), 5 in the example, instead of 1.
