Question

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，我输入：

 from sklearn.model_selection import StratifiedKFold

弹出以下错误消息：

  File "<ipython-input-307-7880cb661350>", line 1, in <module>

ImportError: cannot import name stable_cumsum

Answer 1

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

sklearn ImportError：无法导入名称stable_cumsum
