Running example file

[ntropy-esa]

Hello, New user of python. I am trying to run the example given with pycel. I set up an environment with Python 2.7, install pycell, network, numpy, matplotlip dependencies. In a Jupyter notebook, when I run:

    print "Compiling..., starting from D1"
    sp = c.gen_graph('D1',sheet='Sheet1')

I get the error:

Compiling..., starting from D1
Seed D1 expanded into 1 cells
1 filtered seeds 
1 cells on the todo list
Handling  Sheet1!D1
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

    582         else:

TypeError: add_node() takes exactly 2 arguments (3 given)

Sounds very basic, but I can't figure out what is wrong? Not correct version of networkx?

[ntropy-esa]

Basic indeed. Networkx <2.0, not equal. pip uninstall networkx pip install networkx==1.11
