Is there a ready-made neural network for pattern recognition?

Question

Python

Can you upload a finished project with a working neural network for recognizing numbers or letters? I can't find it, please help.

Answer 1

If we are talking about a neural network, about a late graduate student, then it needs to be trained. This is the principle.
If we are talking about a recognition library, then there are plenty of them free of charge.

Answer 2

Good introduction and practice:
Online course "Programming deep neural systems"
