In Python, everything is an object. Certain objects, like functions, are
callable. Other objects, like modules are not. You have a module mapped to
the name "drawffnet". Python tries to call that object, but it isn't
callable. If there is a function drawffnet inside the drawffnet module (I'm
not familiar with the package, so I don't know), you need to call that
