There may be other issues, but one is that referencing an array in a module namespace seems to currently be unsupported (simple repro below). Try importing omega as a name.

In [14]: %%file Sweep.py
    ...: import numpy as np
    ...: constant_val = 0.5
    ...: constant_arr = np.array([0, 1.5, 2.])
Overwriting Sweep.py

In [15]: Sweep.constant_val
Out[15]: 0.5

In [16]: Sweep.constant_arr
Out[16]: array([ 0. ,  1.5,  2. ])

In [17]: @njit
    ...: def f(value):
    ...:     return value + Sweep.constant_val
    ...: 

In [18]: f(100)
Out[18]: 100.5

In [19]: @njit
    ...: def f(value):
    ...:     return value + Sweep.constant_arr[0]

In [20]: f(100)
