Tensorflow Enqueue operation was cancelled

Question

I had built a convolutional neural network in tensorflow. It is trained and now I am unpacking it and performing evaluations.

import main
import Process
import I         


        

Answer 1

Everything works correctly and the problem happens at the very last stage when python tries to kill threads. To do this properly you should create a train.Coordinator and pass it to your queue_runner (no need to pass sess, as default session will be used

with tf.Session() as sess:
    coord = tf.train.Coordinator()
    threads = tf.train.start_queue_runners(coord=coord)
    // do your things
    coord.request_stop()
    coord.join(threads)
