tf.contrib.rnn.LayerRNNCell

Subclass of RNNCells that act like proper tf.Layer objects.

Inherits From: RNNCell

For backwards compatibility purposes, most RNNCell instances allow their call methods to instantiate variables via tf.compat.v1.get_variable. The underlying variable scope thus keeps track of any variables, and returning cached versions. This is atypical of tf.layer objects, which separate this part of layer building into a build method that is only called once.

Here we provide a subclass for RNNCell objects that act exactly as Layer objects do. They must provide a build method and their call methods do not access Variables tf.compat.v1.get_variable.

graph 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.

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.
