What you'll learn
Just what are PyTorch Hooks?
What are hooks in PyTorch? And have you already used them? (Surprisingly: yes)
Why are hooks useful?
Learn the most common ways hooks are currently used and why
Learn to implement them yourself
It's only useful if you know how to do it! We'll make sure by the end you can write your own hooks.
Why this topic matters
Hooks are important in modern Deep Learning, but many (as proven by an earlier X poll) have either: never written one, or even know *what they do*.
Truthfully, if you are using anything in the modern DL space (big model inference, large-scale training) hooks make their way everywhere.
In this lesson, we're going to dive into them and how they're being used around you.
