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: Python3.8 from "C:\Users\VikingsWu\anaconda3\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: DLL load failed while importing _multiarray_umath: 找不到指定的模块。

• Finding a lot of information, including reinstalling Numpy, can not solve the problem; note that VS Code has been executed first conda activate base;

problem solved

• import numpyNo error is reported when executed with Anaconda Prompt (anaconda3) , indicating that there is no problem with numpy;
  

• In Power Shell, the execution conda activate basefails; it prompts that the shell needs to be configured;
  

• Execute conda init powershellcommands to configure Power Shell;
  

• Reopen Power Shell and prompt the following message:

. : 无法加载文件 C:\Users\VikingsWu\Documents\WindowsPowerShell\profile.ps1，因为在此系统上禁止运行脚本。有关详细信息，

• Reference blog: https://blog.csdn.net/l_x_cser/article/details/104956657 to solve this problem;

• Re-open Power Shell, Power Shell automatically enters base, runs python, and executes import numpywithout error, indicating that the problem has been solved, just turn off the automatic activate base;

• Execute the command conda config --set auto_activate_base falseto close the automatic activate_base;

• Reopen the Power Shell, the execution is conda activate basesuccessful, run python, the execution import numpydoes not report an error, the problem is solved;
