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