What is the optimal algorithm for finding people in photos in a VK group?

Question

Python

Good day to all! There was one small issue.
A telegram bot is being developed (python).
A brief algorithm of the bot's work: The user uploads his photo, and the face searches for photos in a specific Vkontakte group. Next, the user is given photos with him.
The development experience is small, but I assume that it is not difficult to organize a bot that accepts photos and connect the face recognition library.

The question arose: how to optimally organize the base for the photo recognition library?
Can I cache all photos on the server or can I do it somehow through the VK API?

Question number two: does anyone know of successful similar projects? I would be very grateful if you could tell me.

I will also be grateful if you give me ideas on the architecture of this bot. I'm sure there are a lot of experienced users here.

In general, I need the advice of experienced colleagues.

Answer 1

A simple Python library ageitgey/face_recognition to get a feel for the domain.

Answer 2

You will have to index all the pictures on the right, then stupidly look for the index
