Returns up to num_records (key, value) pairs produced by a Reader.
tf.raw_ops.ReaderReadUpTo(
    reader_handle, queue_handle, num_records, name=None
)
Will dequeue from the input queue if necessary (e.g. when the
Reader needs to start reading from a new file since it has finished
with the previous file).
It may return less than num_records even before the last batch.
