The code doesn't define 'np', so this line should produce an error.
The code you linked contains this import:
import numpy as np
However you didn't show it here, so I wonder if you posted the real code.

The built-in function sum() returns a single value, not a list, so this
is a reasonable error.
I suspect the code actually intended to call numpy.sum(), which does
return a list (or something like a list).
