WebAug 3, 2024 · LogisticRegresssion with the lbfgs solver terminates early, even when tol is decreased and max_iter has not been reached. Code to Reproduce. We fit random data twice, changing only the order of the examples. Ideally, example order should not matter; the fit coefficients should be the same either way. I produced the results below with this code ...
