Please post the full error not just a summary.

Also please post the actual code...

I get an import error here with no module named Queue.
Which Queue module are you using? Or should it be
spelled queue?

Assuming you meant the standard queue module then
that should be

q.task_done()

When you get an attribute error it's worth trying
dir() on the offending object:

>>> from queue import Queue as Q
>>> dir(Q)
...., task_done,....
>>> help(Q.task_done)
...
