# tensorflow::ops::QueueDequeueMany

`#include <data_flow_ops.h>`

Dequeues `n` tuples of one or more tensors from the given queue.

## Summary

If the queue is closed and there are fewer than `n` elements, then an OutOfRange error is returned.

This operation concatenates queue-element component tensors along the 0th dimension to make a single component tensor. [All](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/ops/all#classtensorflow_1_1ops_1_1_all) of the components in the dequeued tuple will have size `n` in the 0th dimension.

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 `n` elements have been dequeued (or 'timeout_ms' elapses, if specified).

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- handle: The handle to a queue.
- n: The number of tuples to dequeue.
- component_types: The type of each component in a tuple.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r1.15/api_docs/cc/struct/tensorflow/ops/queue-dequeue-many/attrs#structtensorflow_1_1ops_1_1_queue_dequeue_many_1_1_attrs`):

- timeout_ms: If the queue has fewer than n elements, 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.
