StaticRNN class.
StaticRNN class is used to create a StaticRNN. The RNN will have its
own parameters like inputs, outputs, memories, status and length.
The StaticRNN can process a batch of sequence data. The length of each
sample sequence must be equal. The StaticRNN will have its own parameters
like inputs, outputs, memories. **Note that the first dimension of inputs
represents sequence length, and all the sequence length of inputs must be
the same. And the meaning of each axis of input and output are the same.**
Examples:
>>> import paddle.fluid as fluid
>>> import paddle.fluid.layers as layers
>>>
>>> vocab_size, hidden_size=10000, 200
>>> x = layers.data(name="x", shape=[-1, 1, 1], dtype='int64')
>>> x_emb = layers.embedding(
>>> input=x,
>>> size=[vocab_size, hidden_size],
>>> dtype='float32',
>>> is_sparse=False)
>>> x_emb = layers.transpose(x_emb, perm=[1, 0, 2])
>>>
>>> rnn = fluid.layers.StaticRNN()
>>> with rnn.step():
>>> word = rnn.step_input(x_emb)
>>> prev = rnn.memory(shape=[-1, hidden_size], batch_ref = word)
>>> hidden = fluid.layers.fc(input=[word, prev], size=hidden_size, act='relu')
>>> rnn.update_memory(prev, hidden) # set prev to hidden
>>> rnn.step_output(hidden)
>>>
>>> result = rnn()
The StaticRNN will unfold sequence into time steps. Users need to define
how to process each time step during the :code:`with` step.
The :code:`memory` is used as a staging data cross time step. The initial
value of memory can be a variable that is filled with a constant value or
a specified variable.
The StaticRNN can mark multiple variables as its output. Use `rnn()` to
get the output sequence.
