安装 Tensorflow 后 Numpy 停止工作

Question

我最近下载了 Tensorflow，但无法正确安装。我已将其删除并使用 >pip uninstall tensorflow。

现在我想运行我的一些笔记本，但我收到一个错误：原始错误是：无法从 'numpy.core._multiarray_umath' 导入名称'_set_madvise_hugepage' (C:\Users\Brenda \anaconda3\lib\site-packages\numpy\core_multiarray_umath.cp37-win_amd64.pyd)

正如When importing tensorflow, I get the following error: No module named 'numpy.core._multiarray_umath' 所建议的那样，我卸载了 Numpy 并重新安装了它（我尝试了 pip install numpy –upgrade 和 pip install numpy）。错误并没有消失。

更新我的尝试

This is what I tried in my windows commandprompt
•   pip install -U numpy 
--> Requirement already up-to-date: numpy in c:\users\brenda\anaconda3\lib\site-packages (1.19.1)

•   C:\Users\Brenda>import numpy;print numpy.__version__;print numpy.__file__ 
-->  'import' is not recognized as an internal or external command,operable program or batch file.

•   C:\Users\Brenda>numpy.__version__
--> 'numpy.__version__' is not recognized as an internal or external command,operable program or batch file.

•   pip install numpy==1.8
-->     Not usefull since I’m on version 1.9

•   C:\Users\Brenda>sudo pip install numpy --upgrade --ignore-installed
--> 'sudo' is not recognized as an internal or external command, operable program or batch file.

•   C:\Users\Brenda>pip install -U numpy
--> Requirement already up-to-date: numpy in c:\users\brenda\anaconda3\lib\site-packages (1.19.1)

•   C:\Users\Brenda>pip install --target c:\users\brenda\anaconda3\lib\site-packages
--> ERROR: You must give at least one requirement to install (see "pip help install")

•   C:\Users\Brenda>pip uninstall numpy
-->     Successfully uninstalled numpy-1.19.1
C:\Users\Brenda>pip uninstall numpy
WARNING: Skipping numpy as it is not installed.

•   Typing pip list in Jupyter
--> Numpy 1.19.1

我的版本是：

• Python3.7.6
• NumPy 版本为：“1.19.1”

我很确定 Tensorflow 的安装导致了我的问题。

我很高兴没有 Tensorflow，我只需要 Numpy 再次工作。请帮我解决这个问题。

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:

Please note and check the following:

  * The Python version is: Python3.7 from "C:\Users\Brenda\anaconda3\python.exe"
  * The NumPy version is: "1.19.1"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
