ImportError:您正在使用的"scipy"安装似乎已损坏，(无法导入扩展模块)，请尝试重新安

Question

当我试图通过Jupyter笔记本在Python3.9中使用scipy或sklearn包时，我经常收到这个错误。

错误为：

---------------------------------------------------------------------------

The above exception was the direct cause of the following exception:

我尝试过卸载和重新安装scipy，正如文档中所描述的那样，也尝试过使用自制软件，但仍然出现了同样的错误。

有人知道如何解决这个问题吗？Scipy几周前还在我的机器上工作——不确定过去几周发生了什么变化。

非常感谢您的帮助。

Answer 1

对我来说，这是由于防病毒，删除了scipy文件的appdata副本。检查是否有文件_ccallbcak_cp310-win_amd64.pyd从c:\Users\XXXX\AppData\Roaming\Python\Python310\site packages\scipy_lib 被阻止

Answer 2

我也面临同样的问题，但重新安装对我来说很有效。使用Anaconda(或Miniconda(卸载并安装scipy

pip uninstall scipy
pip install scipy

在调试过程中，我还升级了pip并安装了spider，也许它们包含了任何对我有帮助的软件包
