Scipy least squares

WebThe take-home is that, for a simple least-squares problem, and ordinary-looking data, for a particular starting value, `fmin_powell` stops on a not-minimum value and claims success, where other optimizers do find the minimum, as does the Octave implementation. Here is the output from the reproducer:

It doesn't even have to call least_squares. It will hang on this line: from scipy.optimize import least_squares But, when I boil it down to just a simple test program like I've shown here, it works.
