AttributeError: module 'dlib' has no attribute 'get_frontal_face_detector'

This error occurs when the 'get_frontal_face_detector' function is not available in the 'dlib' module. This function is used for detecting frontal faces in images using the Dlib library.

To fix this error, you can try updating your Dlib library to the latest version, as this function may not be available in older versions. You can also try reinstalling the Dlib library to make sure that all the necessary functions are installed.

If the issue persists, it may be worth checking if you have correctly installed all the dependencies required by Dlib. Additionally, you may want to check if there are any conflicts with other installed packages that may be affecting the functionality of Dlib.
