QueueDequeueUpTo
#include <data_flow_ops.h>
Dequeues
n
tuples of one or more tensors from the given queue.
Summary
This operation is not supported by all queues. If a queue does not support DequeueUpTo, then an Unimplemented error is returned.
If the queue is closed and there are more than 0 but less than
n
elements remaining, then instead of returning an OutOfRange error like
QueueDequeueMany
, less than
n
elements are returned immediately. If the queue is closed and there are 0 elements left in the queue, then an OutOfRange error is returned just like in
QueueDequeueMany
. Otherwise the behavior is identical to
QueueDequeueMany
:
This operation concatenates queue-element component tensors along the 0th dimension to make a single component tensor. 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.
Args:
- scope: A 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.
Optional attributes (see
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.
Returns:
-
OutputList
: One or more tensors that were dequeued as a tuple.
