tf.raw_ops.ReaderReadUpToV2

Returns up to num_records (key, value) pairs produced by a Reader.

tf.raw_ops.ReaderReadUpToV2(
    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.

Args:

  • reader_handle: A Tensor of type resource. Handle to a Reader.
  • queue_handle: A Tensor of type resource. Handle to a Queue, with string work items.
  • num_records: A Tensor of type int64. number of records to read from Reader.
  • name: A name for the operation (optional).

Returns:

A tuple of Tensor objects (keys, values).

  • keys: A Tensor of type string.
  • values: A Tensor of type string.
