F:\Program Files\Python\Python36\lib\site-packages\sklearn\linear_model\_logistic.py:764: ConvergenceWarning: lbfgs failed to converge (status=1):
STOP: TOTAL NO. of ITERATIONS REACHED LIMIT.
Increase the number of iterations (max_iter) or scale the data as shown in:
? ? https://scikit-learn.org/stable/modules/preprocessing.html
Please also refer to the documentation for alternative solver options:
? ? https://scikit-learn.org/stable/modules/linear_model.html#logistic-regression
? extra_warning_msg=_LOGISTIC_SOLVER_CONVERGENCE_MSG)
?
?
解決思路
收斂警告:lbfgs無法聚合(狀態(tài)=1):
停止:迭代總數(shù)達(dá)到限制。
增加迭代次數(shù)(最大值)或縮放數(shù)據(jù),如中所示:https://scikit-learn.org/stable/modules/preprocessing.html
另請參閱文檔以了解其他解算器選項:https://scikit-learn.org/stable/modules/linear_model.html#logistic-regression%20%C2%A0%20extra_warning_msg=_LOGISTIC_SOLVER_CONVERGENCE_MSG)

解決方法
迭代總數(shù)達(dá)到限制。增加迭代次數(shù)(最大值)或縮放數(shù)據(jù).scikit-learn版本問題導(dǎo)致的匹配警告和收斂警告,調(diào)用的函數(shù)和方法已經(jīng)有改變,暫時不處理也不會影響程序運行。
建議升級版本或者修改為最新版本的用法,合理使用庫函數(shù)!
