Importing Numpy into functions
As other answers say, you need to import numpy into each file where you call a Numpy function. However you don't need to import it into the main module if you're not using it in the main module. Here's a simple example. Imagine you have a file with your function in it called myFunc.pymyFunc.py:
import numpy as npdef f1(a): # a is a numpy multidimensional array z = np.array(a) flat = z.ravel() flat = flat.tolist() return flat Then in your main file you can do something like this
import myFunc as mfmf.f1([[4,67,8],[7,9,7]])Your output will be:
[4, 67, 8, 7, 9, 7]So you pass a list to your function, convert it to a numpy array in your function, then return the answer as a list. If you return a numpy array you'll get an error.
You have to import modules in every file in which you use them. Does that answer your question?
