You're importing the module 'drawffnet' and then trying to call it in:

     drawffnet(nn)

but, as the traceback says, modules can't be called.

I had a quick look at the documentation and it looks like you should be
calling a function called 'drawffnet' that's defined in the module
called 'drawffnet'. Try doing:

     from ffnet.tools.drawffnet import drawffnet

instead.
