Python：Jupyter Notebook中的Python路径与anaconda3不同

Question

我在这里遇到一个奇怪的问题，请帮助我。

在jupyter笔记本中，我可以import cv2，没有这样的错误：

https://angular-code.azurewebsites.net

但是在Anaconda3文件夹中运行python.exe时，它遇到一个错误：

Python 3.7.3 (default, Mar 27 2019, 17:13:21) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32

>>> import cv2
ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\ADMINS\Anaconda3\lib\site-packages\cv2\__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: numpy.core.multiarray failed to import
>>>

我尝试2件事，首先我将numpy更新为：

C:\Users\ADMINS>pip install --user -U numpy
Requirement already up-to-date: numpy in c:\users\admins\anaconda3\lib\site-packages (1.17.0)

然后我激活环境：

C:\Users\ADMINS>conda activate base

(base) C:\Users\ADMINS>

但是错误仍然存​​在，请帮助我解决它：

(base) C:\Users\ADMINS>python
