Class TfLiteRNNCell

The most basic RNN cell.

Inherits From: LayerRNNCell

Aliases:

This is used only for TfLite, it provides hints and it also makes the variables in the desired for the tflite ops.

__init__

__init__(
    num_units,
    activation=None,
    reuse=None,
    name=None,
    dtype=None,
    **kwargs
)

Initializes the parameters for an RNN cell.

Args:

  • num_units: int, The number of units in the RNN cell.
  • activation: Nonlinearity to use. Default: tanh. It could also be string that is within Keras activation function names.
  • reuse: (optional) Python boolean describing whether to reuse variables in an existing scope. Raises an error if not True and the existing scope already has the given variables.
  • name: String, the name of the layer. Layers with the same name will share weights, but to avoid mistakes we require reuse=True in such cases.
  • dtype: Default dtype of the layer (default of None means use the type of the first input). Required when build is called before call.
  • **kwargs: Dict, keyword named properties for common layer attributes, like trainable etc when constructing the cell from configs of get_config().

Raises:

  • ValueError: If the existing scope already has the given variables.

DEPRECATED FUNCTION

output_size

Integer or TensorShape: size of outputs produced by this cell.

scope_name

state_size

size(s) of state(s) used by this cell.

It can be represented by an Integer, a TensorShape or a tuple of Integers or TensorShapes.

Methods

get_initial_state

get_initial_state(
    inputs=None,
    batch_size=None,
    dtype=None
)

zero_state

View source

zero_state(
    batch_size,
    dtype
)

Return zero-filled state tensor(s).

Args:

  • batch_size: int, float, or unit Tensor representing the batch size.
  • dtype: the data type to use for the state.

Returns:

If state_size is an int or TensorShape, then the return value is a N-D tensor of shape [batch_size, state_size] filled with zeros.

If state_size is a nested list or tuple, then the return value is a nested list or tuple (of the same structure) of 2-D tensors with the shapes [batch_size, s] for each s in state_size.
