Question

我之前安装了scipy，numpy和scikit-learn，这些都运行良好。今天，我用pip install更新了我的所有库。 numpy和scikit-learn更新到最新版本，但scipy有编译问题并被回滚。

当我尝试

时

from sklearn.ensemble import RandomForestClassifier

我得到了

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。我无法做到这一点。

我尝试Failed building wheel for scipy

时

pip install scipy

这是追踪：

我看到缺少库blas和lapack。有没有比安装程序更简单的方法来解决我的错误。我必须为此获得BLAS，LAPACK，ATLAS。

关于我遇到此问题的原因的任何输入，当我尝试更新时，库文件是否被删除了？

谢谢！

在Windows上，如果使用scipy安装pip，则可能会遇到问题。如果您正在运行anaconda，您可以尝试评论中建议的内容：

conda install scipy

或者您可以尝试从here下载最新版本的Windows版本：

Python扩展程序包的非官方Windows二进制文件作者：Christoph Gohlke，加州大学尔湾分校荧光动力学实验室

然后使用pip安装下载的.whl文件。
