 ================
 
 The PaddlePaddle V2 API is designed to provide a modern user interface for PaddlePaddle V1(the original layer-based platform of PaddlePaddle),
-it proposes some high-level concepts such as `Layers<http://www.paddlepaddle.org/docs/develop/api/en/v2/config/layer.html>`_ ,`Optimizer<http://www.paddlepaddle.org/docs/develop/api/en/v2/config/optimizer.html>`_ ,`Evaluator`<http://www.paddlepaddle.org/docs/develop/api/en/v2/config/evaluators.html>`_  and `Data Reader<http://www.paddlepaddle.org/docs/develop/api/en/v2/data/data_reader.html>`_ to make the model configuration more familiar to users.

 A model is composed of the computation described by a group of `Layers`, with `Evaluator` to define the error, `Optimizer` to update the parameters and `Data Reader` to feed in the data.
 
-We also provide the `interface for Training and Inference`<http://www.paddlepaddle.org/docs/develop/api/en/v2/run_logic.html`_ to help control the training and inference phrase,

 it has several easy to use methods
 
 - `paddle.train` 
 - `paddle.test`
 - `paddle.infer`
 
-to better expose the internal running details, different `Events<http://www.paddlepaddle.org/docs/develop/api/en/v2/run_logic.html#event>`_ are available to users by writing some callbacks.
