tf.QueueBase.dequeue_many()

tf.QueueBase.dequeue_many(n, name=None)

Dequeues and concatenates n elements from this queue.

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.

If the queue is closed and there are less than n elements left, then an OutOfRange exception is raised.

At runtime, this operation may raise an error if the queue is closed before or during its execution. If the queue is closed, the queue contains fewer than n elements, and there are no pending enqueue operations that can fulfil this request, tf.errors.OutOfRangeError will be raised. If the session is closed, tf.errors.CancelledError will be raised.

Args:

• n: A scalar Tensor containing the number of elements to dequeue.
• name: A name for the operation (optional).

Returns:

The tuple of concatenated tensors that was dequeued.
