Overview

Created by Jeremy Howard and Rachel Thomas, Practical Deep Learning for Coders flips the usual order: you build and train working models — image classifiers, NLP models, tabular and collaborative-filtering systems — from lesson one, and pick up the underlying theory as you go. It uses the fastai library on top of PyTorch and is beloved for making deep learning feel achievable for working programmers. Entirely free, with an accompanying book.
