Regarding modulenotfounderror no module named cv2 This error may occur if you didn't install opencv module in your system. So first check this module is available or not.

  $ pip list or conda list

If it is not available, then install this module.

$ pip install opencv-python or conda install opencv-python

But before that, try to check numpy module is available or not. If numpy is not available, then install this first.

  $ pip install numpy

Hope this will solve your error.

The "Module Not Found" error, specifically "No Module Named Cv2," typically occurs when trying to import the OpenCV library (cv2) in Python code without it being installed in the current environment. Here's how you can resolve it:

Install OpenCV: First, ensure that you have OpenCV installed in your Python environment. You can install it using pip, the Python package manager, by running the following command in your terminal or command prompt:

pip install opencv-python

If you prefer to install a specific version, you can specify it, for example:

pip install opencv-python==

Verify Installation: Once the installation is complete, you can verify it by importing the cv2 module in a Python script or in an interactive Python session (like IDLE or Jupyter Notebook). Open a Python interpreter and try importing cv2:

  import cv2

If no errors occur upon importing, the installation was successful.

Check Environment: Ensure that you're using the correct Python environment where OpenCV is installed. Sometimes, if you have multiple Python environments (e.g., virtual environments), the module might be installed in one environment but not in another.

By following these steps, you should be able to resolve the "Module Not Found" error and successfully import the cv2 module in your Python code.
