* Here is a simple example of LSTM neural network. ![image](https://user-images.githubusercontent.com/15994006/48116065-db328a00-e29f-11e8-86ed-3cea49114719.png) We need `hl.transforms.Rename()` to rename the RNN node. ```python tsfm = [hl.transforms.Rename(op='prim::PythonOp', to = 'LSTM')] ``` ![image](https://user-images.githubusercontent.com/15994006/48116076-e5ed1f00-e29f-11e8-9307-8671aef8d6e5.png)

1. 建议参考以下中文排版规范,这也是Keras中文文档的规范。 * [chinese-copywriting-guidelines](https://github.com/sparanoid/chinese-copywriting-guidelines/blob/master/README.zh-CN.md) * [Chinese (zh-cn) translation of the Keras documentation.](https://github.com/keras-team/keras-docs-zh) 2. 建议使用 [MkDocs](https://www.mkdocs.org/) 工具将已经完成的 MarkDown 文档发布在 github 的 gh-pages分支。
