ffnet throwing TypeError

[pisaac-ozflux]

Hi mrkwjc,
Many thanks for all your work on FFNET over the years.
I ran into a problem with FFNET today. The exception is below:
TypeError: object of type 'dictionary-keyiterator' has no len()
and is thrown at line 611 of ffnet.py:
n = len(self.graph.predecessors(trg))
The fix I used was to change line 611 of ffnet.py to:
n = len(list(self.graph.predecessors(trg)))
Other details are:
OS: Ubuntu 14.04
Python: Anaconda 2.7 (I can supply a list of installed packages and version numbers if required)
Cheers,
Peter

Tanks for reporting. This problem arises when networkx-2.x is installed. I'll fix it soon...

Yeah, I caught the networkx >= 2 link but figured that a simple hack was better than reverting to an earlier version. Thanks, Peter
