This document provides links to documentation on NumPy support in Numba and an article in Japanese about optimizing NumPy code when using Numba. Numba is a Python compiler that can accelerate NumPy code by compiling Python code with NumPy operations into fast machine code. The documentation and article discuss which NumPy functions and operations are supported in Numba and how to write NumPy code in a way that allows Numba to optimize and accelerate it.
