This a alpha package to lambdify SymPy expressions with Numba
For a showcase see: https://github.com/jankoslavic/numbafy/blob/master/Showcase.ipynb
Simple example:
import sympy as sym
from numba import jit
# this is a very basic example; numbafy shines with huge expression
a, b, c = sym.symbols('a, b, c')
constants = {c: 1.4}
expression = c * a**b
parameters = (a, b)
num = numbafy(expression=expression, parameters=parameters, constants=constants, use_cse=True)
exec(num)
result = numbafy_func(a=2.0, b=3.0)
print(result)
>>> 11.2
For a more complete example with huge expression see the Showcase.ipynb.
