no module name cv2

It seems like you're encountering an error "No module named cv2". This error occurs when the OpenCV library is not installed or not properly imported in your Python environment.

To resolve this issue, you need to install the OpenCV library. You can do this by running the following command in your terminal or command prompt:

pip install opencv-python

Make sure you have pip installed and it is up to date. If you are using a virtual environment, make sure it is activated before running the installation command.

Once the installation is complete, you can import the cv2 module in your Python script without any errors:

import cv2

If you still encounter the same error after installing OpenCV, please make sure that you have installed it correctly and consider checking your Python environment setup.
