- flowrouter.py currently does not work with python3 and this might be what's causing your error. - If you encounter that error using python2.7, make sure that flowrouter.py resides in the sumo/tools/detector folder when being called. - if that still doesn't solve your problem, then some other module which is also called detector must be somewhere on your python load path. If you put something like print(detector.__path__) after the 'import detector' line in flowrouter.py you can find out where it's coming from
