AttributeError: module 'cv2' has no attribute 'VideoCapture'

This error occurs when you try to use the VideoCapture function from the cv2 module, but it is not available in your version of OpenCV.

There are a few possible reasons for this error:

1. You have not installed OpenCV correctly. Make sure you have installed the correct version of OpenCV for your Python environment and operating system.

2. You have a version of OpenCV that does not include the VideoCapture function. This can happen if you have an outdated version of OpenCV or if you installed a stripped-down version that does not include all the functions.

3. There is an issue with your Python environment. Try restarting your Python environment or reinstalling OpenCV.

To fix this error, you can try the following:

1. Check that you have installed OpenCV correctly and that the VideoCapture function is available in your version.

2. Try updating your version of OpenCV to a more recent version that includes the VideoCapture function.

3. If you are using a virtual environment, make sure you activate it before installing OpenCV and using the VideoCapture function.

4. If none of these solutions work, try reinstalling OpenCV and making sure you follow the installation instructions carefully.
