Numba has been installed in the system, but I do the following code times wrong, don't know what the reason, ask for help!
Code:
#! The/usr/bin/env python
# coding: utf-8

The from numba import jit

@ jit (nopython=True)
Def f (x, y) :
# A somewhat trivial example
Return x + y

If __name__=="__main__" :
Print f (1, 2)


Results:
Traceback (the most recent call last) :
