tf.train.queue_runner.start_queue_runners

Starts all queue runners collected in the graph. (deprecated)

Aliases:

tf.train.queue_runner.start_queue_runners(
    sess=None,
    coord=None,
    daemon=True,
    start=True,
    collection=tf.GraphKeys.QUEUE_RUNNERS
)

This is a companion method to add_queue_runner(). It just starts threads for all queue runners collected in the graph. It returns the list of all threads.

Args:

sess: Session used to run the queue ops. Defaults to the default session.
coord: Optional Coordinator for coordinating the started threads.
daemon: Whether the threads should be marked as daemons, meaning they don't block program exit.
start: Set to False to only create the threads, not start them.
collection: A GraphKey specifying the graph collection to get the queue runners from. Defaults to GraphKeys.QUEUE_RUNNERS.

Raises:

ValueError: if sess is None and there isn't any default session.
TypeError: if sess is not a tf.compat.v1.Session object.

Returns:

A list of threads.

Raises:

RuntimeError: If called with eager execution enabled.
ValueError: If called without a default tf.compat.v1.Session registered.

Eager Compatibility

Not compatible with eager execution. To ingest data under eager execution, use the tf.data API instead.
