QueueDequeueMany

`


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/r2.5/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).


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/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/r2.5/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.
