在 python 中导入 cv2 在 vs 代码中不起作用

Question

The python code I wanted to run:

import cv2
print(cv2.__verion__)  

The Error code I am getting:

Windows PowerShell

    Try the new cross-platform PowerShell https://aka.ms/pscore6
    
    PS D:\Programme\Visual Studio\New Projects> & C:/Users/Florian/AppData/Local/Programs/Python/Python310/python.exe "d:/Programme/Visual Studio/New Projects/Python/opencv_test.py"
    Traceback (most recent call last):
      File "d:\Programme\Visual Studio\New Projects\Python\opencv_test.py", line 1, in <module>
        import cv2
    ModuleNotFoundError: No module named 'cv2'

But if I type the exact same code in the Terminal it works:

    PS D:\Programme\Visual Studio\New Projects> python
    Python 3.9.9 (tags/v3.9.9:ccb0e6a, Nov 15 2021, 18:08:50) [MSC v.1929 64 bit (AMD64)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import cv2
    >>> print(cv2.__version__)
    4.5.4
    >>>

So far I installed python via Command Prompt and via Microsoft Store. And currently I am running the verion 3.9.9

PS D:\Programme\Visual Studio\New Projects> python --version
Python 3.9.9

I installed opencv in the Command Prompt:

PS C:\Users\Florian> pip install opencv-python
Requirement already satisfied: opencv-python in c:\users\florian\appdata\local\packages\pythonsoftwarefoundation.python.3.9_qbz5n2kfra8p0\localcache\local-packages\python39\site-packages (4.5.4.60)
Requirement already satisfied: numpy>=1.19.3 in c:\users\florian\appdata\local\packages\pythonsoftwarefoundation.python.3.9_qbz5n2kfra8p0\localcache\local-packages\python39\site-packages (from opencv-python) (1.21.5)
PS C:\Users\Florian>

I searched every Forum I could think of, but cant find a fix.

Please help

Answer 1

I had the same issue in VScode using python 3.9.6. I switched to python 3.10.7 and it worked fine.

Answer 2

in your VScode press Ctrl+Shift+P and then type "Python: Select Interpreter" then select your python Interpreter and Run it again.

Answer 3

Try running pip3.10 install opencv-python .

Because:

• cv2 is a part of opencv-python
• and/or you might not have installed the module in the right python folder version.

Answer 4

I had the same problem and search anywhere for the answer. selecting the right interpreter will solve this problem. you might use vscode by the anaconda, but you should use the python interpreter where you installed it.
