"""Sets up reader, prefetcher and returns input queue.
Args:
batch_size_per_clone: batch size to use per clone.
create_tensor_dict_fn: function to create tensor dictionary.
batch_queue_capacity: maximum number of elements to store within a queue.
num_batch_queue_threads: number of threads to use for batching.
prefetch_queue_capacity: maximum capacity of the queue used to prefetch
assembled batches.
data_augmentation_options: a list of tuples, where each tuple contains a
data augmentation function and a dictionary containing arguments and their
values (see preprocessor.py).
Returns:
input queue: a batcher.BatchQueue object holding enqueued tensor_dicts
(which hold images, boxes and targets). To get a batch of tensor_dicts,
call input_queue.Dequeue().
