This is not properly documented. So I am wondering how to run this code?

http://cvit.iiit.ac.in/research/projects/cvit-projects/speaking-by-observing-lip-movements

 

The GitHub page has all the information and it is very well documented.

Prerequisites

• Python 3.7.4 (code has been tested with this version)
• ffmpeg: sudo apt-get install ffmpeg
• Install necessary packages using pip install -r requirements.txt
• Face detection pre-trained model should be downloaded to face_detection/detection/sfd/s3fd.pth. Alternative link if the above does not work.

Below that is information about the datasets and other things. What are you not finding documented?
