+############
+基本使用概念
+############
+
+PaddlePaddle是源于百度的一个深度学习平台。PaddlePaddle为深度学习研究人员提供了丰富的API，可以轻松地完成神经网络配置，模型训练等任务。
+这里将介绍PaddlePaddle的基本使用概念，并且展示了如何利用PaddlePaddle来解决一个经典的线性回归问题。
+在使用该文档之前，请参考 `安装文档 <../build_and_install/index_cn.html>`_ 完成PaddlePaddle的安装。
+
+
+配置网络
+============
+
+加载PaddlePaddle
+----------------------
+
+在进行网络配置之前，首先需要加载相应的Python库，并进行初始化操作。
+
+..	code-block:: bash
+
+    import paddle.v2 as paddle
+    import numpy as np
+    paddle.init(use_gpu=False)
+
+
+搭建神经网络
+-----------------------
+
+搭建神经网络就像使用积木搭建宝塔一样。在PaddlePaddle中，layer是我们的积木，而神经网络是我们要搭建的宝塔。我们使用不同的layer进行组合，来搭建神经网络。
+宝塔的底端需要坚实的基座来支撑，同样，神经网络也需要一些特定的layer作为输入接口，来完成网络的训练。
+
+例如，我们可以定义如下layer来描述神经网络的输入：
+
+..	code-block:: bash
+
+    x = paddle.layer.data(name='x', type=paddle.data_type.dense_vector(2))
+    y = paddle.layer.data(name='y', type=paddle.data_type.dense_vector(1))
+
+其中x表示输入数据是一个维度为2的稠密向量，y表示输入数据是一个维度为1的稠密向量。
+
+PaddlePaddle支持不同类型的输入数据，主要包括四种类型，和三种序列模式。
+
+四种数据类型：
+
+* dense_vector：稠密的浮点数向量。
+* sparse_binary_vector：稀疏的01向量，即大部分值为0，但有值的地方必须为1。
+* sparse_float_vector：稀疏的向量，即大部分值为0，但有值的部分可以是任何浮点数。
+* integer：整数标签。
+
+三种序列模式：
+
+* SequenceType.NO_SEQUENCE：不是一条序列
+* SequenceType.SEQUENCE：是一条时间序列
+* SequenceType.SUB_SEQUENCE： 是一条时间序列，且序列的每一个元素还是一个时间序列。
+
+不同的数据类型和序列模式返回的格式不同，列表如下：
+
+----------------------+---------------------+-----------------------------------+------------------------------------------------+
+|                      | NO_SEQUENCE         | SEQUENCE                          |  SUB_SEQUENCE                                  |
+======================+=====================+===================================+================================================+
+| dense_vector         | [f, f, ...]         | [[f, ...], [f, ...], ...]         | [[[f, ...], ...], [[f, ...], ...],...]         |
+----------------------+---------------------+-----------------------------------+------------------------------------------------+
+| sparse_binary_vector | [i, i, ...]         | [[i, ...], [i, ...], ...]         | [[[i, ...], ...], [[i, ...], ...],...]         |
+----------------------+---------------------+-----------------------------------+------------------------------------------------+
+| sparse_float_vector  | [(i,f), (i,f), ...] | [[(i,f), ...], [(i,f), ...], ...] | [[[(i,f), ...], ...], [[(i,f), ...], ...],...] |
+----------------------+---------------------+-----------------------------------+------------------------------------------------+
+| integer_value        |  i                  | [i, i, ...]                       | [[i, ...], [i, ...], ...]                      |
+----------------------+---------------------+-----------------------------------+------------------------------------------------+
+
+其中，f代表一个浮点数，i代表一个整数。
+
+注意：对sparse_binary_vector和sparse_float_vector，PaddlePaddle存的是有值位置的索引。例如，
+
+- 对一个5维非序列的稀疏01向量 ``[0, 1, 1, 0, 0]`` ，类型是sparse_binary_vector，返回的是 ``[1, 2]`` 。
+- 对一个5维非序列的稀疏浮点向量 ``[0, 0.5, 0.7, 0, 0]`` ，类型是sparse_float_vector，返回的是 ``[(1, 0.5), (2, 0.7)]`` 。
+
+
+在定义输入layer之后，我们可以使用其他layer进行组合。在组合时，需要指定layer的输入来源。
+
+例如，我们可以定义如下的layer组合：
+
+..	code-block:: bash
+
+    y_predict = paddle.layer.fc(input=x, size=1, act=paddle.activation.Linear())
+    cost = paddle.layer.mse_cost(input=y_predict, label=y)
+
+其中，x与y为之前描述的输入层；而y_predict是接收x作为输入，接上一个全连接层；cost接收y_predict与y作为输入，接上均方误差层。
+
+最后一层cost中记录了神经网络的所有拓扑结构，通过组合不同的layer，我们即可完成神经网络的搭建。
+
+
+训练模型
+============
+
+在完成神经网络的搭建之后，我们首先需要根据神经网络结构来创建所需要优化的parameters，并创建optimizer。
+之后，我们可以创建trainer来对网络进行训练。
+
+..	code-block:: bash
+
+    parameters = paddle.parameters.create(cost)
+    optimizer = paddle.optimizer.Momentum(momentum=0)
+    trainer = paddle.trainer.SGD(cost=cost,
+                                 parameters=parameters,
+                                 update_equation=optimizer)
+
+其中，trainer接收三个参数，包括神经网络拓扑结构、神经网络参数以及迭代方程。
+
+在搭建神经网络的过程中，我们仅仅对神经网络的输入进行了描述。而trainer需要读取训练数据进行训练，PaddlePaddle中通过reader来加载数据。
+
+..	code-block:: bash
+
+    # define training dataset reader
+    def train_reader():
+        train_x = np.array([[1, 1], [1, 2], [3, 4], [5, 2]])
+        train_y = np.array([-2, -3, -7, -7])
+        def reader():
+            for i in xrange(train_y.shape[0]):
+                yield train_x[i], train_y[i]
+        return reader
+
+最终我们可以调用trainer的train方法启动训练：
+
+..	code-block:: bash
+
+    # define feeding map
+    feeding = {'x': 0, 'y': 1}
+
+    # event_handler to print training info
+    def event_handler(event):
+        if isinstance(event, paddle.event.EndIteration):
+            if event.batch_id % 1 == 0:
+                print "Pass %d, Batch %d, Cost %f" % (
+                    event.pass_id, event.batch_id, event.cost)
+    # training
+    trainer.train(
+        reader=paddle.batch(train_reader(), batch_size=1),
+        feeding=feeding,
+        event_handler=event_handler,
+        num_passes=100)
+

-############
-基本使用概念
-############
-
-PaddlePaddle是一个深度学习框架，支持单机模式和多机模式。
-
-单机模式用命令 ``paddle train`` 可以启动一个trainer进程，单机训练通常只包括一个trainer进程。如果数据规模比较大，希望加速训练，可以启动分布式作业。一个分布式作业里包括若干trainer进程和若干Parameter Server（或称pserver）进程。用命令 ``paddle pserver`` 可以启动 pserver 进程，pserver进程用于协调多个trainer进程之间的通信。
-
-本文首先介绍trainer进程中的一些使用概念，然后介绍pserver进程中概念。
-
-..    contents::
-
-系统框图
-========
-
-下图描述了用户使用框图，PaddlePaddle的trainer进程里内嵌了Python解释器，trainer进程可以利用这个解释器执行Python脚本，Python脚本里定义了模型配置、训练算法、以及数据读取函数。其中，数据读取程序往往定义在一个单独Python脚本文件里，被称为数据提供器（DataProvider），通常是一个Python函数。模型配置、训练算法通常定义在另一单独Python文件中, 称为训练配置文件。下面将分别介绍这两部分。
-
-..    graphviz:: 
-
-    digraph pp_process {
-        rankdir=LR;
-        config_file [label="用户神经网络配置"];
-        subgraph cluster_pp {
-            style=filled;
-            color=lightgrey;
-            node [style=filled, color=white, shape=box];
-            label = "PaddlePaddle C++";
-            py [label="Python解释器"];
-        }
-        data_provider [label="用户数据解析"];
-        config_file -> py;
-        py -> data_provider [dir="back"];
-    }
-
-数据提供器
-==========
-
-DataProvider是PaddlePaddle系统的数据提供器，将用户的原始数据转换成系统可以识别的数据类型。每当系统需要新的数据训练时, trainer进程会调用DataProvider函数返回数据。当所有数据读取完一轮后，DataProvider返回空数据，通知系统一轮数据读取结束，并且系统每一轮训练开始时会重置DataProvider。需要注意的是，DataProvider是被系统调用，而不是新数据驱动系统，一些随机化噪声添加都应该在DataProvider中完成。
-
-在不同的应用里，训练数据的格式往往各不相同。因此，为了用户能够灵活的处理数据，我们提供了Python处理数据的接口，称为 ``PyDataProvider`` 。在 ``PyDataProvider`` 中，系统C++模块接管了shuffle、处理batch、GPU和CPU通信、双缓冲、异步读取等问题，一些情况下(如：``min_pool_size=0``)需要Python接口里处理shuffle，可以参考 :ref:`api_pydataprovider2` 继续深入了解。
-
-
-训练配置文件
-============
-
-训练配置文件主要包括数据源、优化算法、网络结构配置三部分。 其中数据源配置与DataProvider的关系是：DataProvider里定义数据读取函数，训练配置文件的数据源配置中指定DataProvider文件名字、生成数据函数接口，请不要混淆。
-
-一个简单的训练配置文件为：
-
-..  literalinclude:: src/trainer_config.py
-    :linenos:
-
-文件开头 ``from paddle.trainer_config_helpers import *`` ，是因为PaddlePaddle配置文件与C++模块通信的最基础协议是protobuf，为了避免用户直接写复杂的protobuf string，我们为用户定以Python接口来配置网络，该Python代码可以生成protobuf包，这就是 :ref:`api_trainer_config` 的作用。因此，在文件的开始，需要import这些函数。 这个包里面包含了模型配置需要的各个模块。
-
-下面分别介绍数据源配置、优化算法配置、网络结构配置这三部分该概念。
-
-数据源配置
----------
-
-使用 ``PyDataProvider2`` 的函数 ``define_py_data_sources2`` 配置数据源。``define_py_data_sources2`` 里通过train_list和test_list指定是训练文件列表和测试文件列表。 如果传入字符串的话，是指一个数据列表文件。这个数据列表文件中包含的是每一个训练或者测试文件的路径。如果传入一个list的话，则会默认生成一个list文件，再传入给train.list或者test.list。
-
-``module`` 和 ``obj`` 指定了DataProvider的文件名和返回数据的函数名。更详细的使用，请参考 :ref:`api_pydataprovider2` 。
-
-优化算法配置
------------
-
-通过 :ref:`api_trainer_config_helpers_optimizers_settings` 接口设置神经网络所使用的训练参数和 :ref:`api_trainer_config_helpers_optimizers` ，包括学习率、batch_size、优化算法、正则方法等，具体的使用方法请参考 :ref:`api_trainer_config_helpers_optimizers_settings` 文档。
-
-网络结构配置
------------
-
-神经网络配置主要包括网络连接、激活函数、损失函数、评估器。
-
- 网络连接： 主要由Layer组成，每个Layer返回的都是一个 ``LayerOutput`` 对象，Layer里面可以定义参数属性、激活类型等。
-
-  为了更灵活的配置，PaddlePaddle提供了基于 Projection 或者 Operator 的配置，这两个需要与 ``mixed_layer`` 配合使用。这里简单介绍Layer、Projection、Operator的概念:
-
-  - Layer: 神经网络的某一层，可以有可学习的参数，一般是封装了许多复杂操作的集合。
-  - Projection：需要与 ``mixed_layer`` 配合使用，含可学习参数。
-  - Operator： 需要与 ``mixed_layer`` 配合使用，不含可学习参数，输入全是其他Layer的输出。
-
- 
-  这个配置文件网络由 ``data_layer`` 、 ``simple_img_conv_pool`` 、 ``fc_layer`` 组成。
-
-  - :ref:`api_trainer_config_helpers_layers_data_layer`  ： 通常每个配置文件都会包括 ``data_layer`` ，定义输入数据大小。
-  - :ref:`api_trainer_config_helpers_network_simple_img_conv_pool` ：是一个组合层，包括了图像的卷积 (convolution)和池化(pooling)。
-  - :ref:`api_trainer_config_helpers_layers_fc_layer` ：全连接层，激活函数为Softmax，这里也可叫分类层。
-
- 损失函数和评估器：损失函数即为网络的优化目标，评估器可以评价模型结果。
-
-  PaddlePaddle包括很多损失函数和评估起，详细可以参考 :ref:`api_trainer_config_helpers_layers_cost_layers` 和 :ref:`api_trainer_config_helpers_evaluators` 。这里 ``classification_cost`` 默认使用多类交叉熵损失函数和分类错误率统计评估器。
-  
- ``outputs``: 标记网络输出的函数为 ``outputs`` 。
-
-  训练阶段，网络的输出为神经网络的优化目标；预测阶段，网络的输出也可通过 ``outputs`` 标记。
-
-
-这里对 ``mixed_layer`` 稍做详细说明， 该Layer将多个输入(Projection 或 Operator)累加求和，具体计算是通过内部的 Projection 和 Operator 完成，然后加 Bias 和 activation 操作，
-
-例如，和 ``fc_layer`` 同样功能的 ``mixed_layer`` 是:
-
-..    code-block:: python
-   
-       data = data_layer(name='data', size=200)
-       with mixed_layer(size=200) as out:
-           out += full_matrix_projection(input=data)
-
-PaddlePaddle 可以使用 ``mixed layer`` 配置出非常复杂的网络，甚至可以直接配置一个完整的LSTM。用户可以参考 :ref:`api_trainer_config_helpers_layers_mixed_layer` 的相关文档进行配置。
-
-
-分布式训练
-==========
-
-PaddlePaddle多机采用经典的 Parameter Server 架构对多个节点的 trainer 进行同步。多机训练的经典拓扑结构如下\:
-
-..    graphviz:: src/pserver_topology.dot
-
-图中每个灰色方块是一台机器，在每个机器中，先使用命令 ``paddle pserver`` 启动一个pserver进程，并指定端口号，可能的参数是\:
-
-..    code-block:: bash
-
-    paddle pserver --port=5000 --num_gradient_servers=4 --tcp_rdma='tcp' --nics='eth0'
-
-* ``--port=5000`` : 指定 pserver 进程端口是 5000 。
-* ``--gradient_servers=4`` : 有四个训练进程(PaddlePaddle 将 trainer 也称作 GradientServer ，因为其为负责提供Gradient) 。
-* ``--tcp_rdma='tcp' --nics=`eth0```: 指定以太网类型为TCP网络，指定网络接口名字为eth0。
-
-启动之后 pserver 进程之后，需要启动 trainer 训练进程，在各个机器上运行如下命令\:
-
-..    code-block:: bash
-
-    paddle train --port=5000 --pservers=192.168.100.101,192.168.100.102,192.168.100.103,192.168.100.104 --config=...
-
-对于简单的多机协同训练使用上述方式即可。另外，pserver/train 通常在高级情况下，还需要设置下面两个参数\：
-
-* --ports_num\: 一个 pserver 进程共绑定多少个端口用来做稠密更新，默认是1。
-* --ports_num_for_sparse\: 一个pserver进程共绑定多少端口用来做稀疏更新，默认是0。
-
-使用手工指定端口数量，是因为Paddle的网络通信中，使用了 int32 作为消息长度，比较容易在大模型下溢出。所以，在 pserver 进程中可以启动多个子线程去接受 trainer 的数据，这样单个子线程的长度就不会溢出了。但是这个值不可以调的过大，因为增加这个值，对性能尤其是内存占用有一定的开销，另外稀疏更新的端口如果太大的话，很容易导致某一个参数服务器没有分配到任何参数。

+<h1>基本使用概念<a class="headerlink" href="#id1" title="永久链接至标题">¶</a></h1>
+<p>PaddlePaddle是源于百度的一个深度学习平台。PaddlePaddle为深度学习研究人员提供了丰富的API，可以轻松地完成神经网络配置，模型训练等任务。
+这里将介绍PaddlePaddle的基本使用概念，并且展示了如何利用PaddlePaddle来解决一个经典的线性回归问题。
+在使用该文档之前，请参考 <a class="reference external" href="../build_and_install/index_cn.html">安装文档</a> 完成PaddlePaddle的安装。</p>

+<h3>加载PaddlePaddle<a class="headerlink" href="#paddlepaddle" title="永久链接至标题">¶</a></h3>
+<p>在进行网络配置之前，首先需要加载相应的Python库，并进行初始化操作。</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>import paddle.v2 as paddle
+import numpy as np
+paddle.init<span class="o">(</span><span class="nv">use_gpu</span><span class="o">=</span>False<span class="o">)</span>

+<div class="section" id="id4">
+<h3>搭建神经网络<a class="headerlink" href="#id4" title="永久链接至标题">¶</a></h3>
+<p>搭建神经网络就像使用积木搭建宝塔一样。在PaddlePaddle中，layer是我们的积木，而神经网络是我们要搭建的宝塔。我们使用不同的layer进行组合，来搭建神经网络。
+宝塔的底端需要坚实的基座来支撑，同样，神经网络也需要一些特定的layer作为输入接口，来完成网络的训练。</p>
+<p>例如，我们可以定义如下layer来描述神经网络的输入：</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">x</span> <span class="o">=</span> paddle.layer.data<span class="o">(</span><span class="nv">name</span><span class="o">=</span><span class="s1">&#39;x&#39;</span>, <span class="nv">type</span><span class="o">=</span>paddle.data_type.dense_vector<span class="o">(</span><span class="m">2</span><span class="o">))</span>
+<span class="nv">y</span> <span class="o">=</span> paddle.layer.data<span class="o">(</span><span class="nv">name</span><span class="o">=</span><span class="s1">&#39;y&#39;</span>, <span class="nv">type</span><span class="o">=</span>paddle.data_type.dense_vector<span class="o">(</span><span class="m">1</span><span class="o">))</span>
+</pre></div>
+</div>
+<p>其中x表示输入数据是一个维度为2的稠密向量，y表示输入数据是一个维度为1的稠密向量。</p>
+<p>PaddlePaddle支持不同类型的输入数据，主要包括四种类型，和三种序列模式。</p>
+<p>四种数据类型：</p>
+<ul class="simple">
+<li>dense_vector：稠密的浮点数向量。</li>
+<li>sparse_binary_vector：稀疏的01向量，即大部分值为0，但有值的地方必须为1。</li>
+<li>sparse_float_vector：稀疏的向量，即大部分值为0，但有值的部分可以是任何浮点数。</li>
+<li>integer：整数标签。</li>
+</ul>
+<p>三种序列模式：</p>
+<ul class="simple">
+<li>SequenceType.NO_SEQUENCE：不是一条序列</li>
+<li>SequenceType.SEQUENCE：是一条时间序列</li>
+<li>SequenceType.SUB_SEQUENCE： 是一条时间序列，且序列的每一个元素还是一个时间序列。</li>
+</ul>
+<p>不同的数据类型和序列模式返回的格式不同，列表如下：</p>
+<table border="1" class="docutils">
+<colgroup>
+<col width="17%" />
+<col width="17%" />
+<col width="28%" />
+<col width="38%" />
+</colgroup>
+<thead valign="bottom">
+<tr class="row-odd"><th class="head">&#160;</th>
+<th class="head">NO_SEQUENCE</th>
+<th class="head">SEQUENCE</th>
+<th class="head">SUB_SEQUENCE</th>
+</tr>
+</thead>
+<tbody valign="top">
+<tr class="row-even"><td>dense_vector</td>
+<td>[f, f, ...]</td>
+<td>[[f, ...], [f, ...], ...]</td>
+<td>[[[f, ...], ...], [[f, ...], ...],...]</td>
+</tr>
+<tr class="row-odd"><td>sparse_binary_vector</td>
+<td>[i, i, ...]</td>
+<td>[[i, ...], [i, ...], ...]</td>
+<td>[[[i, ...], ...], [[i, ...], ...],...]</td>
+</tr>
+<tr class="row-even"><td>sparse_float_vector</td>
+<td>[(i,f), (i,f), ...]</td>
+<td>[[(i,f), ...], [(i,f), ...], ...]</td>
+<td>[[[(i,f), ...], ...], [[(i,f), ...], ...],...]</td>
+</tr>
+<tr class="row-odd"><td>integer_value</td>
+<td>i</td>
+<td>[i, i, ...]</td>
+<td>[[i, ...], [i, ...], ...]</td>
+</tr>
+</tbody>
+</table>
+<p>其中，f代表一个浮点数，i代表一个整数。</p>
+<p>注意：对sparse_binary_vector和sparse_float_vector，PaddlePaddle存的是有值位置的索引。例如，</p>
+<ul class="simple">
+<li>对一个5维非序列的稀疏01向量 <code class="docutils literal"><span class="pre">[0,</span> <span class="pre">1,</span> <span class="pre">1,</span> <span class="pre">0,</span> <span class="pre">0]</span></code> ，类型是sparse_binary_vector，返回的是 <code class="docutils literal"><span class="pre">[1,</span> <span class="pre">2]</span></code> 。</li>
+<li>对一个5维非序列的稀疏浮点向量 <code class="docutils literal"><span class="pre">[0,</span> <span class="pre">0.5,</span> <span class="pre">0.7,</span> <span class="pre">0,</span> <span class="pre">0]</span></code> ，类型是sparse_float_vector，返回的是 <code class="docutils literal"><span class="pre">[(1,</span> <span class="pre">0.5),</span> <span class="pre">(2,</span> <span class="pre">0.7)]</span></code> 。</li>
+</ul>
+<p>在定义输入layer之后，我们可以使用其他layer进行组合。在组合时，需要指定layer的输入来源。</p>
+<p>例如，我们可以定义如下的layer组合：</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">y_predict</span> <span class="o">=</span> paddle.layer.fc<span class="o">(</span><span class="nv">input</span><span class="o">=</span>x, <span class="nv">size</span><span class="o">=</span><span class="m">1</span>, <span class="nv">act</span><span class="o">=</span>paddle.activation.Linear<span class="o">())</span>
+<span class="nv">cost</span> <span class="o">=</span> paddle.layer.mse_cost<span class="o">(</span><span class="nv">input</span><span class="o">=</span>y_predict, <span class="nv">label</span><span class="o">=</span>y<span class="o">)</span>
+</pre></div>
+</div>
+<p>其中，x与y为之前描述的输入层；而y_predict是接收x作为输入，接上一个全连接层；cost接收y_predict与y作为输入，接上均方误差层。</p>
+<p>最后一层cost中记录了神经网络的所有拓扑结构，通过组合不同的layer，我们即可完成神经网络的搭建。</p>
+</div>
+</div>
+<div class="section" id="id5">
+<h2>训练模型<a class="headerlink" href="#id5" title="永久链接至标题">¶</a></h2>
+<p>在完成神经网络的搭建之后，我们首先需要根据神经网络结构来创建所需要优化的parameters，并创建optimizer。
+之后，我们可以创建trainer来对网络进行训练。</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">parameters</span> <span class="o">=</span> paddle.parameters.create<span class="o">(</span>cost<span class="o">)</span>

+<span class="nv">trainer</span> <span class="o">=</span> paddle.trainer.SGD<span class="o">(</span><span class="nv">cost</span><span class="o">=</span>cost,
+                             <span class="nv">parameters</span><span class="o">=</span>parameters,
+                             <span class="nv">update_equation</span><span class="o">=</span>optimizer<span class="o">)</span>
+</pre></div>
+</div>
+<p>其中，trainer接收三个参数，包括神经网络拓扑结构、神经网络参数以及迭代方程。</p>
+<p>在搭建神经网络的过程中，我们仅仅对神经网络的输入进行了描述。而trainer需要读取训练数据进行训练，PaddlePaddle中通过reader来加载数据。</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="c1"># define training dataset reader</span>
+def train_reader<span class="o">()</span>:
+    <span class="nv">train_x</span> <span class="o">=</span> np.array<span class="o">([[</span><span class="m">1</span>, <span class="m">1</span><span class="o">]</span>, <span class="o">[</span><span class="m">1</span>, <span class="m">2</span><span class="o">]</span>, <span class="o">[</span><span class="m">3</span>, <span class="m">4</span><span class="o">]</span>, <span class="o">[</span><span class="m">5</span>, <span class="m">2</span><span class="o">]])</span>

-<p>PaddlePaddle是一个深度学习框架，支持单机模式和多机模式。</p>
-<p>单机模式用命令 <code class="docutils literal"><span class="pre">paddle</span> <span class="pre">train</span></code> 可以启动一个trainer进程，单机训练通常只包括一个trainer进程。如果数据规模比较大，希望加速训练，可以启动分布式作业。一个分布式作业里包括若干trainer进程和若干Parameter Server（或称pserver）进程。用命令 <code class="docutils literal"><span class="pre">paddle</span> <span class="pre">pserver</span></code> 可以启动 pserver 进程，pserver进程用于协调多个trainer进程之间的通信。</p>
-<p>本文首先介绍trainer进程中的一些使用概念，然后介绍pserver进程中概念。</p>

-<p>下图描述了用户使用框图，PaddlePaddle的trainer进程里内嵌了Python解释器，trainer进程可以利用这个解释器执行Python脚本，Python脚本里定义了模型配置、训练算法、以及数据读取函数。其中，数据读取程序往往定义在一个单独Python脚本文件里，被称为数据提供器（DataProvider），通常是一个Python函数。模型配置、训练算法通常定义在另一单独Python文件中, 称为训练配置文件。下面将分别介绍这两部分。</p>

-<h2><a class="toc-backref" href="#id11">数据提供器</a><a class="headerlink" href="#id3" title="永久链接至标题">¶</a></h2>
-<p>DataProvider是PaddlePaddle系统的数据提供器，将用户的原始数据转换成系统可以识别的数据类型。每当系统需要新的数据训练时, trainer进程会调用DataProvider函数返回数据。当所有数据读取完一轮后，DataProvider返回空数据，通知系统一轮数据读取结束，并且系统每一轮训练开始时会重置DataProvider。需要注意的是，DataProvider是被系统调用，而不是新数据驱动系统，一些随机化噪声添加都应该在DataProvider中完成。</p>
-<p>在不同的应用里，训练数据的格式往往各不相同。因此，为了用户能够灵活的处理数据，我们提供了Python处理数据的接口，称为 <code class="docutils literal"><span class="pre">PyDataProvider</span></code> 。在 <code class="docutils literal"><span class="pre">PyDataProvider</span></code> 中，系统C++模块接管了shuffle、处理batch、GPU和CPU通信、双缓冲、异步读取等问题，一些情况下(如：<code class="docutils literal"><span class="pre">min_pool_size=0</span></code>)需要Python接口里处理shuffle，可以参考 <a class="reference internal" href="../../../api/v1/data_provider/pydataprovider2_cn.html#api-pydataprovider2"><span class="std std-ref">PyDataProvider2的使用</span></a> 继续深入了解。</p>

-<p>文件开头 <code class="docutils literal"><span class="pre">from</span> <span class="pre">paddle.trainer_config_helpers</span> <span class="pre">import</span> <span class="pre">*</span></code> ，是因为PaddlePaddle配置文件与C++模块通信的最基础协议是protobuf，为了避免用户直接写复杂的protobuf string，我们为用户定以Python接口来配置网络，该Python代码可以生成protobuf包，这就是 <a class="reference internal" href="../../../api/v1/index_cn.html#api-trainer-config"><span class="std std-ref">Model Config API</span></a> 的作用。因此，在文件的开始，需要import这些函数。 这个包里面包含了模型配置需要的各个模块。</p>

-<p>神经网络配置主要包括网络连接、激活函数、损失函数、评估器。</p>
-<ul>
-<li><p class="first">网络连接： 主要由Layer组成，每个Layer返回的都是一个 <code class="docutils literal"><span class="pre">LayerOutput</span></code> 对象，Layer里面可以定义参数属性、激活类型等。</p>
-<p>为了更灵活的配置，PaddlePaddle提供了基于 Projection 或者 Operator 的配置，这两个需要与 <code class="docutils literal"><span class="pre">mixed_layer</span></code> 配合使用。这里简单介绍Layer、Projection、Operator的概念:</p>
-<ul class="simple">
-<li>Layer: 神经网络的某一层，可以有可学习的参数，一般是封装了许多复杂操作的集合。</li>
-<li>Projection：需要与 <code class="docutils literal"><span class="pre">mixed_layer</span></code> 配合使用，含可学习参数。</li>
-<li>Operator： 需要与 <code class="docutils literal"><span class="pre">mixed_layer</span></code> 配合使用，不含可学习参数，输入全是其他Layer的输出。</li>
-</ul>
-<p>这个配置文件网络由 <code class="docutils literal"><span class="pre">data_layer</span></code> 、 <code class="docutils literal"><span class="pre">simple_img_conv_pool</span></code> 、 <code class="docutils literal"><span class="pre">fc_layer</span></code> 组成。</p>
-<ul class="simple">
-<li><a class="reference internal" href="../../../api/v1/trainer_config_helpers/layers.html#api-trainer-config-helpers-layers-data-layer"><span class="std std-ref">data_layer</span></a>  ： 通常每个配置文件都会包括 <code class="docutils literal"><span class="pre">data_layer</span></code> ，定义输入数据大小。</li>
-<li><a class="reference internal" href="../../../api/v2/config/networks.html#api-trainer-config-helpers-network-simple-img-conv-pool"><span class="std std-ref">simple_img_conv_pool</span></a> ：是一个组合层，包括了图像的卷积 (convolution)和池化(pooling)。</li>
-<li><a class="reference internal" href="../../../api/v1/trainer_config_helpers/layers.html#api-trainer-config-helpers-layers-fc-layer"><span class="std std-ref">fc_layer</span></a> ：全连接层，激活函数为Softmax，这里也可叫分类层。</li>
-</ul>
-</li>
-<li><p class="first">损失函数和评估器：损失函数即为网络的优化目标，评估器可以评价模型结果。</p>
-<p>PaddlePaddle包括很多损失函数和评估起，详细可以参考 <a class="reference internal" href="../../../api/v1/trainer_config_helpers/layers.html#api-trainer-config-helpers-layers-cost-layers"><span class="std std-ref">Cost Layers</span></a> 和 <a class="reference internal" href="../../../api/v1/trainer_config_helpers/evaluators.html#api-trainer-config-helpers-evaluators"><span class="std std-ref">Evaluators</span></a> 。这里 <code class="docutils literal"><span class="pre">classification_cost</span></code> 默认使用多类交叉熵损失函数和分类错误率统计评估器。</p>
-</li>
-<li><p class="first"><code class="docutils literal"><span class="pre">outputs</span></code>: 标记网络输出的函数为 <code class="docutils literal"><span class="pre">outputs</span></code> 。</p>
-<p>训练阶段，网络的输出为神经网络的优化目标；预测阶段，网络的输出也可通过 <code class="docutils literal"><span class="pre">outputs</span></code> 标记。</p>
-</li>
-</ul>
-<p>这里对 <code class="docutils literal"><span class="pre">mixed_layer</span></code> 稍做详细说明， 该Layer将多个输入(Projection 或 Operator)累加求和，具体计算是通过内部的 Projection 和 Operator 完成，然后加 Bias 和 activation 操作，</p>
-<p>例如，和 <code class="docutils literal"><span class="pre">fc_layer</span></code> 同样功能的 <code class="docutils literal"><span class="pre">mixed_layer</span></code> 是:</p>
-<div class="highlight-python"><div class="highlight"><pre><span></span><span class="n">data</span> <span class="o">=</span> <span class="n">data_layer</span><span class="p">(</span><span class="n">name</span><span class="o">=</span><span class="s1">&#39;data&#39;</span><span class="p">,</span> <span class="n">size</span><span class="o">=</span><span class="mi">200</span><span class="p">)</span>
-<span class="k">with</span> <span class="n">mixed_layer</span><span class="p">(</span><span class="n">size</span><span class="o">=</span><span class="mi">200</span><span class="p">)</span> <span class="k">as</span> <span class="n">out</span><span class="p">:</span>

-<p>PaddlePaddle 可以使用 <code class="docutils literal"><span class="pre">mixed</span> <span class="pre">layer</span></code> 配置出非常复杂的网络，甚至可以直接配置一个完整的LSTM。用户可以参考 <a class="reference internal" href="../../../api/v1/trainer_config_helpers/layers.html#api-trainer-config-helpers-layers-mixed-layer"><span class="std std-ref">mixed_layer</span></a> 的相关文档进行配置。</p>

-<p>图中每个灰色方块是一台机器，在每个机器中，先使用命令 <code class="docutils literal"><span class="pre">paddle</span> <span class="pre">pserver</span></code> 启动一个pserver进程，并指定端口号，可能的参数是:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>paddle pserver --port<span class="o">=</span><span class="m">5000</span> --num_gradient_servers<span class="o">=</span><span class="m">4</span> --tcp_rdma<span class="o">=</span><span class="s1">&#39;tcp&#39;</span> --nics<span class="o">=</span><span class="s1">&#39;eth0&#39;</span>
-</pre></div>
-</div>
-<ul class="simple">
-<li><code class="docutils literal"><span class="pre">--port=5000</span></code> : 指定 pserver 进程端口是 5000 。</li>
-<li><code class="docutils literal"><span class="pre">--gradient_servers=4</span></code> : 有四个训练进程(PaddlePaddle 将 trainer 也称作 GradientServer ，因为其为负责提供Gradient) 。</li>
-<li><code class="docutils literal"><span class="pre">--tcp_rdma='tcp'</span> <span class="pre">--nics=`eth0`</span></code>: 指定以太网类型为TCP网络，指定网络接口名字为eth0。</li>
-</ul>
-<p>启动之后 pserver 进程之后，需要启动 trainer 训练进程，在各个机器上运行如下命令:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>paddle train --port<span class="o">=</span><span class="m">5000</span> --pservers<span class="o">=</span><span class="m">192</span>.168.100.101,192.168.100.102,192.168.100.103,192.168.100.104 --config<span class="o">=</span>...
-</pre></div>
-</div>
-<p>对于简单的多机协同训练使用上述方式即可。另外，pserver/train 通常在高级情况下，还需要设置下面两个参数：</p>
-<ul class="simple">
-<li>&#8211;ports_num: 一个 pserver 进程共绑定多少个端口用来做稠密更新，默认是1。</li>
-<li>&#8211;ports_num_for_sparse: 一个pserver进程共绑定多少端口用来做稀疏更新，默认是0。</li>
-</ul>
-<p>使用手工指定端口数量，是因为Paddle的网络通信中，使用了 int32 作为消息长度，比较容易在大模型下溢出。所以，在 pserver 进程中可以启动多个子线程去接受 trainer 的数据，这样单个子线程的长度就不会溢出了。但是这个值不可以调的过大，因为增加这个值，对性能尤其是内存占用有一定的开销，另外稀疏更新的端口如果太大的话，很容易导致某一个参数服务器没有分配到任何参数。</p>
