我想从sklearn导入StratifiedKFold进行交叉验证.我的电脑使用scikit-learn 0.18.
在 python控制台中,我键入：

from sklearn.model_selection import StratifiedKFold

弹出以下错误消息：

    from ..utils.extmath import stable_cumsum

ImportError: cannot import name stable_cumsum

解决方法

问题已经解决：

删除scikit-learn：

conda remove scikit-learn

然后重新安装：

pip install -U scikit-learn
