I wrote a code in Tkinter that should execute the function of face recognition as soon as the user click on the button and simultaneously it should redirect to the next frame.
What the problem I am currently facing is, when the user clicks on the button, the face recognition function, that is in my code gen(), executes first and as soon as it terminates, it redirects to the next frame.
What I want is both should work at the same time.. Any suggestion please?
