Numba is an open source JIT compiler that translates a subset of

Python and NumPy code into fast machine code. Numba translates

Python functions to optimized machine code at runtime using the

Industry-standard LLVM compiler library. Numba-compiled numerical

algorithms in Python can approach the speeds of C or FORTRAN.

Users do not need to replacethe Python interpreter, run a separate

compilation step, or even have a C/C++ compiler installed. Applying

one of the Numba decorators to a Python function is all that is needed.
