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 notTrue
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 ofNone
means use the type of the first input). Required whenbuild
is called beforecall
.**kwargs
: Dict, keyword named properties for common layer attributes, liketrainable
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
tf.lite.experimental.nn.TfLiteRNNCell.get_initial_state
get_initial_state(
inputs=None,
batch_size=None,
dtype=None
)
tf.lite.experimental.nn.TfLiteRNNCell.zero_state
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
.
