Numba is an just-in-time specializing compiler which compiles annotated Python and NumPy code to LLVM (through decorators). Its goal is to seamlessly integrate with the Python scientific software stack and produce optimized native code, as well as integrate with native foreign languages.
from numba import jit from numpy import arange # jit decorator tells Numba to compile this function. # The argument types will be inferred by Numba when function is called. @jit def sum2d(arr): M, N = arr.shape result = 0.0 for i in range(M): for j in range(N): result += arr[i,j] return result a = arange(9).reshape(3,3) print(sum2d(a))
