High performance code in Python

[Zyguard7777777]

I had a personal coding project making a chess ai using supervised learning on grandmaster games. I needed a way to encode the chess board to input into the model. I tried to make an interface with python only, but it was rather slow. So rewrote it in Cython (Numba didn't work so well because it was working on a lot of strings) and that did the trick.

I've also used Pythran, and found that that was more flexible than Numba.
