Conditionally creates batches of tensors based on keep_input. (deprecated)

    tensors, keep_input, batch_size, num_threads=1, capacity=32, enqueue_many=False,
    shapes=None, dynamic_pad=False, allow_smaller_final_batch=False,
    shared_name=None, name=None

See docstring in batch for more details.


  • tensors: The list or dictionary of tensors to enqueue.
  • keep_input: A bool Tensor. This tensor controls whether the input is added to the queue or not. If it is a scalar and evaluates True, then tensors are all added to the queue. If it is a vector and enqueue_many is True, then each example is added to the queue only if the corresponding value in keep_input is True. This tensor essentially acts as a filtering mechanism.
  • batch_size: The new batch size pulled from the queue.
  • num_threads: The number of threads enqueuing tensors. The batching will be nondeterministic if num_threads > 1.
  • capacity: An integer. The maximum number of elements in the queue.
  • enqueue_many: Whether each tensor in tensors is a single example.
  • shapes: (Optional) The shapes for each example. Defaults to the inferred shapes for tensors.
  • dynamic_pad: Boolean. Allow variable dimensions in input shapes. The given dimensions are padded upon dequeue so that tensors within a batch have the same shapes.
  • allow_smaller_final_batch: (Optional) Boolean. If True, allow the final batch to be smaller if there are insufficient items left in the queue.
  • shared_name: (Optional). If set, this queue will be shared under the given name across multiple sessions.
  • name: (Optional) A name for the operations.


A list or dictionary of tensors with the same types as tensors.


  • ValueError: If the shapes are not specified, and cannot be inferred from the elements of tensors.
