Web4 Nov 2024 · The quick gist is to use scipy.optimize.Bounds in an optimizer that supports this argument such as 'trust-constr', along with the insight that it allows the use of np.inf. You just set some of the bounds to be -np.inf and np.inf for the unbounded parameters, and set the bounds to be 0 and np.inf for the non-negative parameters.
