Defined in tensorflow/python/training/queue_runner_impl.py.

See the guide: Reading data > QueueRunner

Adds a QueueRunner to a collection in the graph. (deprecated)

THIS FUNCTION IS DEPRECATED. It will be removed in a future version. Instructions for updating: To construct input pipelines, use the tf.data module.

When building a complex model that uses many queues it is often difficult to gather all the queue runners that need to be run. This convenience function allows you to add a queue runner to a well known collection in the graph.

The companion method start_queue_runners() can be used to start threads for all the collected queue runners.


  • qr: A QueueRunner.
  • collection: A GraphKey specifying the graph collection to add the queue runner to. Defaults to GraphKeys.QUEUE_RUNNERS.
