PyTorch Internals: Ezyang's Blog

Great article, thanks for posting. Here’s a nice summary of automatic differentiation, mentioned in the article and core to how NN’s are implemented: https://medium.com/@rhome/automatic-differentiation-26d5a993...

2019. How much of this is still relevant?

I’m guessing about 80%

To understand a complex system, sometimes it better to understand a (simpler) model system. Sometimes an older version of the same system is that good model system. This is not true always but a good rule of thumb.

I used this to onboard to the PyTorch team a few years ago. It’s useful for understanding the key concepts of the framework. Torch.compile isn’t covered but the rest of it is still pretty relevant.

For someone it might help: If you are having trouble reading long articles, try text-to-audio with line highlight. It helps a lot. It has cured my lack of attention.
