成功解决ConvergenceWarning: lbfgs failed to converge (status=1): STOP: TOTAL NO. of ITERATIONS REACHED L

解决问题

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:

解决思路

收敛警告：lbfgs无法聚合（状态=1）：

停止：迭代总数达到限制。

增加迭代次数（最大值）或缩放数据，如中所示：https://scikit-learn.org/stable/modules/preprocessing.html

另请参阅文档以了解其他解算器选项：https://scikit-learn.org/stable/modules/linear_model.html#logistic-regression%20%C2%A0%20extra_warning_msg=_LOGISTIC_SOLVER_CONVERGENCE_MSG)

解决方法

迭代总数达到限制。增加迭代次数（最大值）或缩放数据.scikit-learn版本问题导致的匹配警告和收敛警告，调用的函数和方法已经有改变，暂时不处理也不会影响程序运行。

建议升级版本或者修改为最新版本的用法，合理使用库函数！
