I write a simple test code:

import paddle.v2 as paddle
from paddle.v2.layer import parse_network

data = paddle.layer.data(
    name="x", type=paddle.data_type.dense_vector_sequence(128))

lstm = paddle.networks.lstmemory_group(
    input=data,
    memory_boot=paddle.layer.data(
        name="boot", type=paddle.data_type.dense_vector(128)))

print parse_network(lstm)

Here is the outputs, it can be found that memory_boot of lstmemory_group is not created.
