Dequeues n
tuples of one or more tensors from the given queue.
tf.raw_ops.QueueDequeueUpToV2(
handle, n, component_types, timeout_ms=-1, name=None
)
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.
