# tensorflow::ops::QueueDequeue Class Reference

# tensorflow::ops::QueueDequeue

`#include <data_flow_ops.h>`

Dequeues a tuple of one or more tensors from the given queue.

## Summary

This operation has k outputs, where k is the number of components in the tuples stored in the given queue, and output i is the ith component of the dequeued tuple.

N.B. If the queue is empty, this operation will block until an element has been dequeued (or 'timeout_ms' elapses, if specified).

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- handle: The handle to a queue.
- component_types: The type of each component in a tuple.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r2.3/api_docs/cc/struct/tensorflow/ops/queue-dequeue/attrs#structtensorflow_1_1ops_1_1_queue_dequeue_1_1_attrs`):

- timeout_ms: If the queue is empty, this operation will block for up to timeout_ms milliseconds. Note: This option is not supported yet.

<br />

Returns:

- `OutputList`: One or more tensors that were dequeued as a tuple.
