QueueDequeueUpTo

public final class QueueDequeueUpTo

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

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.

Constant Value: "QueueDequeueUpToV2"

Public Methods

public List<Output<?>> components ()

One or more tensors that were dequeued as a tuple.

public static QueueDequeueUpTo create (Scope scope, Operand<?> handle, Operand<TInt32> n, List<Class<? extends TType>> componentTypes, Options... options)

Factory method to create a class wrapping a new QueueDequeueUpTo operation.

Parameters
scope current scope
handle The handle to a queue.
n The number of tuples to dequeue.
componentTypes The type of each component in a tuple.
options carries optional attributes values
Returns
  • a new instance of QueueDequeueUpTo

public Iterator<Operand<TType>> iterator ()

public static QueueDequeueUpTo.Options timeoutMs (Long timeoutMs)

Parameters
timeoutMs 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.
