import queue is lowercase q in Python 3.

Change Q to q and it will be fine.

(See code in for smart switching.)

Queue is in the multiprocessing module so:

from multiprocessing import Queue 

I solve the problem my issue was I had file named queue.py in the same directory

It's because of the Python version. In Python 2.x it's import Queue as queue; on the contrary in Python 3 it's import queue. If you want it for both environments you may use something below as mentioned here

try: import queue except ImportError: import Queue as queue 

In my case it should be:

from multiprocessing import JoinableQueue

Since in python2, Queue has methods like .task_done(), but in python3 multiprocessing.Queue doesn't have this method, and multiprocessing.JoinableQueue does.

I run into the same problem and learn that queue module defines classes and exceptions, that defines the public methods (Queue Objects).

Ex.

workQueue = queue.Queue(10) 

I just copy the file name Queue.py in the */lib/python2.7/ to queue.py and that solved my problem.
