Jupyter notebook 无法在jupyter笔记本中导入numpy

我在jupyter笔记本上运行某个模型，但我的电脑突然崩溃了。重新启动计算机后，我无法在jupyter笔记本中导入numpy，并出现以下错误：

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: Python3.8 from "C:\Users\miniconda3\envs\fraud_detection\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.

Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

我试图删除整个anaconda和jupyter笔记本，但仍然没有成功。奇怪的是，当我在conda命令shell中启动python时，我可以成功导入numpy。非常感谢您的帮助！！

我对python 3.8.8 numpy 1.20.1也有同样的问题，我对python 3.8.8 numpy 1.20.1也有同样的问题
