How Are These Diagrams Made? I'm working on a my first paper right now which has quite a few diagrams. So far I've been able to get by using tikz, but my last two digrams are quite a bit more complicated than the first two and I'm afraid I wont be able to get the look I want from tikz. I came across this blog post where they were able to achieve the look I want, but I cannot find any references to how they made their diagrams. Could anyone point me in the right direction? It seems to be less about machine learning and more about academia so I figured here is the best place to ask.

Here is the blog post: http://jalammar.github.io/illustrated-bert/
Hi thanks for all the comments!

I asked the author on Twitter and it turns out the he uses Keynote to make those diagrams, and not some obscure library written in python or TeX.
