scikit-learn - 导入错误 : No module named 'sklearn.__check_build._check_build'

Question

ModuleNotFoundError                       Traceback (most recent call last)
~\AppData\Roaming\Python\Python36\site-packages\sklearn\__check_build\__init__.py in <module>()

     43 try:
---> 44     from ._check_build import check_build  # noqa
     45 except ImportError as e:

ModuleNotFoundError: No module named 'sklearn.__check_build._check_build'

在处理上述异常的过程中，又发生了一个异常:

似乎 scikit-learn 没有正确构建。

如果您已经从源代码安装了 scikit-learn，请不要忘记
在使用之前构建包:运行 python setup.py install或者 make在源目录中。

如果您使用过安装程序，请检查它是否适合您
Python 版本、您的操作系统和您的平台。

我最近在同一台机器上使用了pycharm并下载了其中的包。从那一刻起，我的 jupyter 笔记本中出现了上述错误。

尝试安装 scipy 并重新启动 python shell
