Imported py file can't find modules it uses

I have an util.py file. There's a function func in it:

import pandas as pd
import numpy as np

def delete_columns(data, columns):
    """
    Deletes all columns in data 
    """
    for column in columns:
        del data[column]

If I import it in my jupyter notebook and implement it - everything is OK.

But then I deside to make another util2 which calls util:

import numpy as np
from util import *
def clean(data):
    data = data[np.isfinite(data.lol)]
    delete_columns(data=data, columns= ['1','2','3'])

And NOW, when i call it from jupyter it finishes with:

----> 7 from user_functions import *
      8 def clean_1(data):
      9     data = data[np.isfinite(data.lol)]

NameError: name 'np' is not defined

What's wrong? Each file imports all modules!

you should import np in modules that's using it, change your util.py to this:

import numpy as np

def func(l):
    a = np.array(l)
    return a

UPDATE: make sure you have numpy for python3 installed (open python3 interpreter (make sure it's python3) and import numpy see if it works (also make sure jupiter is using python 3)
