在windows上安装scipy的问题

Question

我之前安装了scipy, numpy和scikit-learn，它们都工作得很好。今天，我用pip安装更新了所有的库。Numpy和scikit-learn更新到最新版本，但scipy有编译问题，被回滚。

当我尝试

from sklearn.ensemble import RandomForestClassifier

我

ImportError: No module named 'format'

我试图解决这个问题，但它对我不起作用。

所以，我卸载了scipy，这样我就可以重新安装而不会出现任何错误。我不能这样做。

当我尝试pip install scipy时

我看到图书馆的blas和lapack都不见了。有一个更简单的方法来解决我的错误，而不是从安装程序。我得找BLAS, LAPACK, ATLAS。

关于为什么我面临这个问题的任何输入，当我试图更新时，库文件被删除了吗?

谢谢!

在Windows操作系统下，使用pip安装scipy可能会出现问题。如果您正在运行anaconda，您可以尝试评论中的建议:

conda install scipy

或者你可以尝试从这里下载最新的scipy的Windows版本:

然后使用pip安装下载的.whl文件
