sklearn ImportError：无法导入名称stable_cumsum

我想从sklearn导入StratifiedKFold以进行交叉验证。我的电脑使用scikit-learn 0.18。在Python控制台，I型：sklearn ImportError：无法导入名称stable_cumsum

from sklearn.model_selection import StratifiedKFold

以下错误消息弹出：

的问题已经得到解决：

删除scikit学习：

conda remove scikit-learn

然后重新安装它：

pip install -U scikit-learn

你最好用'conda'而不是'pip'重新安装它 – MMF

@MMF如果'conda'安装的那个不起作用？ – BlackJack

卸载并重新安装使用conda和pip后，我仍然看到此问题 –
