| Args | |
|---|---|
| initialize_fn | callable that returns (finished, next_inputs)for the first iteration. | 
| sample_fn | callable that takes (time, outputs, state)and emits tensorsample_ids. | 
| next_inputs_fn | callable that takes (time, outputs, state, sample_ids)and emits(finished, next_inputs, next_state). | 
| sample_ids_shape | Either a list of integers, or a 1-D Tensor of type int32, the shape of each value in thesample_idsbatch. Defaults to
a scalar. | 
| sample_ids_dtype | The dtype of the sample_idstensor. Defaults to int32. |
