AttributeError: 'DiGraph' object has no attribute 'node'

I upgraded my python version from 3.6 to 3.7. The code below throws error:

from koala.ExcelCompiler import ExcelCompiler
from koala.Spreadsheet import Spreadsheet
sp = Spreadsheet("data/Data Warehouse T-Shirt Size.xlsx")

The error is:

    sp = Spreadsheet("data/Data Warehouse T-Shirt Size.xlsx")

Try (as temp fix):

pip uninstall networkx

then

pip install networkx==2.1

Looking at Koala's setup.py file:

install_requires=[
   'networkx >= 2.1',
    ...
]

The current version on networkx is 2.6.3 so i guess something broke between 2.1 & 2.6.3, so....

install_requires=[
   'networkx == 2.1',
    ...
]
