ID Verification on Video Game

Hi all, I am new to learning Python programming language, and i am working on a gaming project in which face ID verification is required to open the game, I write a code and when i try to compile the code, the code run successfully but the face recognition is not working properly, i try to find the solution on the internet and found a page of a company that sells id verification, this helps me a little bit. But my problem is not solved yet, can anyone please help me with this?

Thank you
