The error message "No module named 'cv2'" indicates that the OpenCV (cv2) library is not installed or cannot be found by the Python interpreter. To resolve this issue, you need to install OpenCV on your system and make sure that it is added to the Python path.
You can install OpenCV using pip or conda depending on your Python environment. Here are the steps to install OpenCV using pip:
1. Open your terminal or command prompt and run the following command to install OpenCV:
```
pip install opencv-python
```
2. Once the installation is complete, run the following command to check if OpenCV is installed correctly:
```
import cv2
print(cv2.__version__)
```
If OpenCV is installed correctly, you should see the version number printed on the screen. If you still get the error, try adding the OpenCV library path to the Python path or reinstalling OpenCV.
Note: If you're using a virtual environment, make sure that you have activated it before installing OpenCV.
