Operator adding input embedding to the given cell.

Inherits From: RNNCell

tf.contrib.rnn.EmbeddingWrapper(
    cell, embedding_classes, embedding_size, initializer=None, reuse=None
)

cell an RNNCell, an embedding will be put before its inputs.
embedding_classes integer, how many symbols will be embedded.
embedding_size integer, the size of the vectors we embed into.
initializer an initializer to use when creating the embedding; if None, the initializer from variable scope or a default one is used.
reuse (optional) Python boolean describing whether to reuse variables in an existing scope. If not True, and the existing scope already has the given variables, an error is raised.

TypeError if cell is not an RNNCell.
ValueError if embedding_classes is not positive.

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.

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

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.
