-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, ...], ...] | -+----------------------+---------------------+-----------------------------------+------------------------------------------------+ -

-init_hook -+++++++++ - -init_hook可以传入一个函数。该函数在初始化的时候会被调用，其参数如下: - -* 第一个参数是settings对象，它和数据传入函数的第一个参数（如本例中 ``process`` 函数的 ``settings`` 参数）必须一致。该对象具有以下两个属性： - * settings.input_types：数据输入格式，具体请参考 `input_types`_ 。 - * settings.logger：一个logging对象。 -* 其他参数使用 ``kwargs`` （key word arguments）传入，包括以下两种： - * PaddlePaddle定义的参数: 1）is_train：bool型参数，表示用于训练或预测；2）file_list：所有文件列表。 - * 用户定义的参数：使用args在网络配置中设置。 - -注意：PaddlePaddle保留添加参数的权力，因此init_hook尽量使用 ``**kwargs`` 来接受不使用的函数以保证兼容性。 - -cache -+++++ - -PyDataProvider2提供了两种简单的Cache策略： - -* CacheType.NO_CACHE：不缓存任何数据，每次都会从python端读取数据 -* CacheType.CACHE_PASS_IN_MEM：第一个pass会从python端读取数据，剩下的pass会直接从内存里 - 读取数据。 - - -注意事项 --------- - -可能的内存泄露问题 -++++++++++++++++++ - -PaddlePaddle将train.list中的每一行都传递给process函数，从而生成多个generator。当训练数据非常多时，就会生成非常多的generator。 - -虽然每个generator在没有调用的时候，是几乎不占内存的；但当调用过一次后，generator便会存下当前的上下文(Context)，而这个Context可能会非常大。并且，generator至少需要调用两次才会知道是否停止。所以，即使process函数里面只有一个yield，也需要两次随机选择到相同generator的时候，才会释放该段内存。 - -.. code-block:: python - - def func(): - yield 0 - - f = func() # 创建generator - tmp = next(f) # 调用一次，返回0 - tmp = next(f) # 调用第二次的时候，才会Stop Iteration - -由于顺序调用这些generator不会出现上述问题，因此有两种解决方案： - -1. **最佳推荐**：将样本的地址放入另一个文本文件，train.list写入那个文本文件的地址。即不要将每一个样本都放入train.list。 -2. 在generator的上下文中尽量留下非常少的变量引用，例如 - -.. code-block:: python - - def real_process(fn): - # ... read from fn - return result # 当函数返回的时候，python可以解除掉内部变量的引用。 - - def process(fn): - yield real_process(fn) - -注意：这个问题是PyDataProvider读数据时候的逻辑问题，很难整体修正。 - -内存不够用的情况 -++++++++++++++++ - -PyDataProvider2会尽可能多的使用内存。因此，对于内存较小的机器，推荐使用 ``pool_size`` 变量来设置内存中暂存的数据条。具体请参考 `@provider`_ 中的说明。 - diff --git a/doc/api/v1/data_provider/pydataprovider2_en.rst b/doc/api/v1/data_provider/pydataprovider2_en.rst deleted file mode 100644 index e8fb6292779790765154502bff319ea10ab1e70b..0000000000000000000000000000000000000000 --- a/doc/api/v1/data_provider/pydataprovider2_en.rst +++ /dev/null @@ -1,249 +0,0 @@ -.. _api_pydataprovider2: -

The object contains several attributes, including: - - * :code:`settings.input_types`: the input types. Reference `input_types`_. - * :code:`settings.logger`: a logging object. - -* The rest parameters are the key word arguments. It is made up of PaddpePaddle - pre-defined parameters and user defined parameters. - - * PaddlePaddle-defined parameters including: - - * :code:`is_train` is a bool parameter that indicates the DataProvider is used in - training or testing. - * :code:`file_list` is the list of all files. - - * User-defined parameters args can be set in training configuration. - -Note, PaddlePaddle reserves the right to add pre-defined parameter, so please -use :code:`**kwargs` in init_hook to ensure compatibility by accepting the -parameters which your init_hook does not use. - -cache -+++++ -DataProvider provides two simple cache strategy. They are: - -* :code:`CacheType.NO_CACHE` means do not cache any data, then data is read at runtime by - the user implemented python module every pass. -* :code:`CacheType.CACHE_PASS_IN_MEM` means the first pass reads data by the user - implemented python module, and the rest passes will directly read data from - memory. diff --git a/doc/api/v1/data_provider/src/mnist_config.py b/doc/api/v1/data_provider/src/mnist_config.py deleted file mode 100644 index d2af9d849ec48347d4d56c2b5b6b517671c37518..0000000000000000000000000000000000000000 --- a/doc/api/v1/data_provider/src/mnist_config.py +++ /dev/null @@ -1,24 +0,0 @@ -# Copyright (c) 2018 PaddlePaddle Authors.

-1. 初始化PaddlePaddle环境 - - 在程序开始阶段，通过调用 ``swig_paddle.initPaddle()`` 并传入相应的命令行参数初始化PaddlePaddle。 - -2. 解析模型配置文件 - - 初始化之后，可以通过调用 ``parse_config()`` 解析训练模型时用的配置文件。注意预测数据通常不包含label, 同时预测网络通常直接输出最后一层的结果而不是像训练网络一样再接一层cost layer，所以一般需要对训练用的模型配置文件稍作相应修改才能在预测时使用。 - -3. 构造paddle.GradientMachine - - 通过调用 ``swig_paddle.GradientMachine.createFromConfigproto()`` 传入上一步解析出来的模型配置就可以创建一个 ``GradientMachine``。 - -4. 准备预测数据 - - swig_paddle中的预测接口的参数是自定义的C++数据类型，py_paddle里面提供了一个工具类 ``DataProviderConverter`` 可以用于接收和PyDataProvider2一样的输入数据并转换成预测接口所需的数据类型。 - -5. 模型预测 - - 通过调用 ``forwardTest()`` 传入预测数据，直接返回计算结果。 - - -预测Demo --------- - -如下是一段使用mnist model来实现手写识别的预测代码。完整的代码见 ``src_root/doc/ui/predict/predict_sample.py`` 。mnist model可以通过 ``src_root\demo\mnist`` 目录下的demo训练出来。 -
