RuntimeError: ('Coordinator stopped with threads still running: %s', 'Thread-4 Thread-6 Thread-8')

Traceback (most recent call last):
File "train.py", line 171, in

File "train.py", line 167, in main
coord.join(threads)

RuntimeError: ('Coordinator stopped with threads still running: %s', 'Thread-4 Thread-6 Thread-8')

I tried with the solution in http://stackoverflow.com/questions/36210162/tensorflow-stopping-threads-via-coordinator-seems-not-to-work, but now work.

Add "sess.run(queue.close())" before the line "coord.request_stop()" solve the issue.
