ModuleNotFoundError

[ecrespo]

Following the following link:
http://nbviewer.jupyter.org/gist/vatsan/dd88abb47c2fbd9e16bd
I import:
from pymadlib.pymadlib import *

And I get the following error:

from pymadlib.pymadlib import *
Traceback (most recent call last):
   File "", line 1, in
   File "/home/ernesto/desarrollo/pymadlib/pymadlib/pymadlib.py", line 12, in
     from utils import pivotCategoricalColumns, convertsColsToArray
ModuleNotFoundError: No module named 'utils

Checking the source code does not have utils to import pivotCategoricalColumns.
