ModuleNotFoundError No module named cv2

This error indicates that the cv2 module is not installed or not found in your Python environment.

To resolve this issue, you can try the following steps:

Install OpenCV: OpenCV is often referred to as cv2 in Python. You can install it using the following command in your terminal or command prompt:
```
pip install opencv-python
```
Check the Python environment: Make sure that you are running your code in the correct Python environment where OpenCV is installed. You can check the Python environment by running the following command in your terminal or command prompt:
```
python --version
```
Check the module name: Double-check that you are importing the module correctly in your code. The correct import statement should be:
```
import cv2
```

If you have already installed OpenCV and are still encountering this error, it is possible that there is an issue with your Python environment or installation. In this case, you may need to reinstall Python or troubleshoot your environment setup.
