我就是无法在Python/Anaconda中导入sklearn。
我什么都试过了。已卸载所有Python安装。使用pip重新安装所有库。没有快乐。然后我尝试了Anaconda(只为我安装(。同样的事情-安装了scikit learn，但导入sklearn提供了以下内容：我看到了其他类似的帖子，但也没有从中获得乐趣。请帮忙！

我找到了一个解决方案：https://stackoverflow.com/a/56678933/14674913提示：$> conda remove --force numpy, scipy $> pip install numpy $> pip install scipy
这对我有效。
