Witryna3 sie 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. 2) In my experience, solver not "liblinear" requires more max_iter iterations to converge given the same input data. 3) I didn't see any 'max_iter set in your code snippet. It currently defaults to 100` (sklearn 0.22). 4) I saw you set the the regularization parameter C=100000.
