[FIXED] Jupyter Notebook: Importing function from local module and external modules not defined

Issue

Using Jupyter notebooks, I wish to import a local function from a .py file that utilises functions from an external package (numpy). I am able to successfully import the function, however the imported function seems to not have access to other functions. It should be noted that within the notebook environment I am able to use the numpy functions as expected and np.linspace(3,10,10) outputs the correct array.

Below is a simple function made (in .py file in same directory) to demonstrate the problem:

def numpy_ran(x):
    print('---> TEXT TO SHOW FUNCTION SUCCESSFULLY IMPORTED <---')
    return np.linspace(x,10,10)

Below is the Jupyter notebook cell contents:

from <name of my file> import numpy_test
import numpy as np
numpy_ran(3)

And finally the error message:

---> TEXT TO SHOW FUNCTION SUCCESSFULLY IMPORTED <---

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-3-295710e81feb> in <module>
----> 1 numpy_ran(3)

~\Documents\sam\GANx\numpytest.py in numpy_ran(x)
      1 def numpy_ran(x):
      2     print('function is loading properly')
----> 3     return np.linspace(x,10,10)

NameError: name 'np' is not defined

I have added a screenshot to explain the issue further (not enough rep to embed the image directly).

Any help would really be appreciated, thanks in advance.

Solution

Please add

import numpy as np

to numpytest.py.
