tf.contrib.seq2seq.Helper

Class Helper

Defined in tensorflow/contrib/seq2seq/python/ops/helper.py.

See the guide: Seq2seq Library (contrib) > Dynamic Decoding

Interface for implementing sampling in seq2seq decoders.

Helper instances are used by BasicDecoder.

Properties

batch_size

Batch size of tensor returned by sample.

Returns a scalar int32 tensor.

sample_ids_dtype

DType of tensor returned by sample.

Returns a DType.

sample_ids_shape

Shape of tensor returned by sample, excluding the batch dimension.

Returns a TensorShape.

Methods

initialize

initialize(name=None)

Returns (initial_finished, initial_inputs).

next_inputs

next_inputs(
    time,
    outputs,
    state,
    sample_ids,
    name=None
)

Returns (finished, next_inputs, next_state).

sample

sample(
    time,
    outputs,
    state,
    name=None
)

Returns sample_ids.
