When talking to colleagues I realized that not everyone knows about einsum, my favorite function for developing deep learning models. This post is trying to change that once and for all! :) Einstein summation (einsum) is implemented in numpy, as well as deep learning libraries such as TensorFlow and, thanks to Thomas Viehmann, recently also PyTorch. For background reading on einsum, I recommend the excellent blog posts by Olexa Bilaniuk and Alex Riley. While their posts discuss einsum in the context of numpy, I am going to illustrate how einsum is extremely useful for writing elegant PyTorch/TensorFlow models.1
