A sequence model takes sequences as its input. A sequence is made up of several

with 'time'. It can also be explained to that the order of data are taken into
with time. It can also be explained to that the order of data are taken into

@provider
+++++++++
'@provider' is a Python `Decorator`_, it can construct a PyDataProvider in
PaddlePaddle from a user defined function. Its parameters are:
* `input_types`_ defines format of the data input.
* should_shuffle defines whether to shuffle data or not. By default, it is set
true during training, and false during testing.
* pool_size is the memory pool size (in sample number) in DataProvider.
-1 means no limit.
* can_over_batch_size defines whether PaddlePaddle can store little more
samples than pool_size. It is better to set True to avoid some deadlocks.
* calc_batch_size is a function define how to calculate batch size. This is
usefull in sequential model, that defines batch size is counted upon sequence
or token. By default, each sample or sequence counts to 1 when calculating
batch size.
* cache is a data cache strategy, see `cache`_.
* Init_hook function is invoked once the data provider is initialized,
see `init_hook`_.

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。
即如果train.list中，有100个训练文件，即会生成100个generator。这个本身不是一个很
严重的问题。
但是，如果在训练时，每一条训练数据都是一个文件，并且，训练数据非常多的情况下，就
会生成多个generator。每个generator在没有调用的时候，是几乎不占内存的。但是，当调
用过一次的时候，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至少调用两次才会知道是否停止。所以，即使在process里面只会有一
个yield，也需要两次随机选择到同样的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
而如果按顺序调用这些generator就不会出现这个问题。
所以最佳实践推荐不要将每一个样本都放入train.list。而是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。 或者在python 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)
这个问题是PyDataProvider读数据时候的逻辑问题，基本上不能整体修正。
内存不够用的情况
++++++++++++++++
PyDataProvider2会尽量使用内存。所以如果对于内存比较小的机器，推荐设置
:code:`pool_size` 变量，而这个变量推荐大于训练的batch size，并且在内存足够
的情况下越大越好。
