TypeError: 'int' object is not iterable

On Ubuntu 18.04 I get the following error with any input file from the example:

Hey markus, first of all, thanks for using this tool. I wrote this several years ago and I am not actively maintaining it anymore, because I have a lot of stuff on my plate since then. You are welcome to submit a pull request which I would happily merge if it solves your problem.

(The input file looks okay to my eyes, so it probably is a bug)

I can reproduce this issue:

@christiangoltz Python 2.7 is supported right ?

I've added a few print to understand what's going on:

e

0
<type 'int'>

I can try to fix this issue but I need some guidance as I'm not really familiar with the code. Do you know what the variable e should look like ?

Maybe something has changed in networkx ?

Thanks 😉
