openCV module not found

Description

What steps will reproduce the problem?

I am trying to run a simple program to access my webcam and capture an image. While I can access it from the terminal but I have got a lot of problems in Spyder to do so. I have tried installing the library with miniconda but then I get the kernel error.

FInally, it worked after I uninstalled everything from miniconda, python3.9 and python related folders inside the framework folder except python 2.7 (which is macos default).

Following would installed via the terminal

1. Installed Homebrew and cleanedup
2. Python3 - brew install python
3. created the python environment named pyenv inside a directory other than /opt and I made sure this time I install all packages within this
4. installed the numpy, opencv-python etc packages via pip
5. installed spyder via terminal - pip install spyder

Viola! It works fine as I wanted.

Thanks for the support guys.
