无法从 Sklearn 导入 LinearRegression

Question

from sklearn.linear_model import LinearRegression

在 Jupyter Notebook 中给了我这个错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

我可以很好地从 sklearn.preprocessing 导入东西。谢谢你的帮助！

不知道确切的问题是什么，但卸载并重新安装 scikit-learn 为我解决了这个问题：

pip uninstall scikit-learn
pip install scikit-learn
