【问题描述】：
我一直在我的 Windows 上使用 Anaconda 和 VS Code，一切都很好，直到我的电脑崩溃了。在那之后，我无法运行以前运行良好的脚本。
例如，我现在在运行时遇到错误：

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "C:\Users\myname\AppData\Local\Programs\Python\Python39\python.exe"
* The NumPy version is: "1.19.2"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
我已经阅读了多个帖子，但找不到解决方案。我尝试了多种方法：
-
我已经卸载并重新安装了 anconda
-
我已将 C:\Users\myname\AppData\Local\Programs\Python\Python39 添加到我的系统变量路径中
-
使用 pip 卸载 numpy，然后使用 conda 安装 numpy
-
在 VS 代码中将我的 python 路径设置为 C:\Users\myname\AppData\Local\Programs\Python\Python39 (pythn 版本 3.9.4) 或 C:\Users\myname\anaconda3 (Python 版本 3.8.5 )
-
我转到错误消息中提到的链接但找不到解决方案
-
试图升级我的 numpy 版本（我有 1.20.2）
(pip install numpy --upgrade 要求已经是最新的：c:\users\myname\anaconda3\lib\site-packages (1.20.2) 中的 numpy)
-
Python 版本：3.8.5 和 3.9.4（都试过了）
-
Numpy 版本：1.20.1
-
Matplotlib 版本：3.4.1
这个
import os
print(sys.version)
print("PYTHONPATH:", os.environ.get('PYTHONPATH'))
print("PATH:", os.environ.get('PATH'))
导致这个输出：
