tf.contrib.seq2seq.Helper

Interface for implementing sampling in seq2seq decoders.

Helper instances are used by BasicDecoder.

Attributes
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.
