"""
DataFeeder converts the data that returned by a reader into a data
structure that can feed into Executor and ParallelExecutor. The reader
usually returns a list of mini-batch data entries. Each data entry in
the list is one sample. Each sample is a list or a tuple with one
feature or multiple features.
The simple usage shows below:
.. code-block:: python
place = fluid.CPUPlace()
img = fluid.layers.data(name='image', shape=[1, 28, 28])
label = fluid.layers.data(name='label', shape=[1], dtype='int64')
feeder = fluid.DataFeeder([img, label], fluid.CPUPlace())
result = feeder.feed([([0] * 784, [9]), ([1] * 784, [1])])
If you want to feed data into GPU side separately in advance when you
use multi-GPU to train a model, you can use `decorate_reader` function.
.. code-block:: python
place=fluid.CUDAPlace(0)
feeder = fluid.DataFeeder(place=place, feed_list=[data, label])
reader = feeder.decorate_reader(
paddle.batch(flowers.train(), batch_size=16))
Args:
feed_list(list): The Variables or Variables'name that will
feed into model.
place(Place): place indicates feed data into CPU or GPU, if you want to
feed data into GPU, please using `fluid.CUDAPlace(i)` (`i` represents
the GPU id), or if you want to feed data into CPU, please using
`fluid.CPUPlace()`.
program(Program): The Program that will feed data into, if program
is None, it will use default_main_program(). Default None.
Raises:
ValueError: If some Variable is not in this Program.
Examples:
.. code-block:: python

] # feed_vars_name is a list of variables' name.

Create a lod tensor from a numpy array, a list, or an existing lod tensor.
Create a lod tensor by doing the following:

input (Variable): The input image with [N, C, H, W] format.
conv_num_filter(list|tuple): Indicates the numbers of filter of this group.

a list or tuple, its length must be equal to the length of conv_num_filter.

conv_num_filter. Otherwise, conv_with_batchnorm indicates whether all the
Conv2d Layer follows a BatchNorm. Default False.
conv_batchnorm_drop_rate (float|list): Indicates the drop_rate of Dropout Layer
after BatchNorm. If conv_batchnorm_drop_rate is a list, its length must be
equal to the length of conv_num_filter. Otherwise, drop_rate of all Dropout
Layers is conv_batchnorm_drop_rate. Default 0.0.
pool_stride (int|list|tuple): The pooling stride of Pool2d layer. If pool_stride
is a list or tuple, it must contain two integers, (pooling_stride_H,
pooling_stride_W). Otherwise, the pooling_stride_H = pooling_stride_W = pool_stride.
Default 1.
pool_type (str): Pooling type can be :math:`max` for max-pooling and :math:`avg` for
average-pooling. Default :math:`max`.

simple neural network easily.
This API takes a :code:`train_func`. A :code:`train_func` is a function that
return loss as it first return value. The reset value can be fetched by
EndStepEvent.metrics
This API also takes a :code:`optimizer_func` that will return an optimizer
instance.
For example, to train a MLP for MNIST dataset, the sample program is
>>> import paddle.fluid as fluid
>>>
>>> def mlp(image, layer_sizes=[200, 100], activation="relu", num_classes=10):
>>> hidden = image
>>> for layer_size in layer_sizes:
>>> hidden = fluid.layers.fc(input=hidden, size=layer_size, act=activation)
>>> return fluid.layers.fc(input=hidden, size=num_classes, act="softmax")
>>>
>>> def train_mnist_mlp():
>>> img = fluid.layers.data(name='image', shape=[784])
>>> label = fluid.layers.data(name='label', shape=[1], dtype='int64')
>>> prediction = mlp(img)
>>> return fluid.layers.mean(fluid.layers.cross_entropy(prediction, label))
>>>
>>> def optimizer():
>>> return fluid.optimizer.Adam()
>>>
>>> trainer = Trainer(train_func=train_mnist_mlp,
>>> optimizer_func=optimizer,
>>> place=fluid.CUDAPlace(0),
>>> parallel=True)
>>>
>>> def train_callback(event):
>>> if isinstance(event, fluid.EndStepEvent):
>>> print "Epoch ID", event.epoch, "Step ID",\
>>> event.step, "AvgLoss", event.metrics[0]
>>> elif isinstance(event, fluid.EndEpochEvent):
>>> trainer.save_params("./model_{0}".format(event.epoch))
>>>
>>> trainer.train(num_epochs=100, event_handler=train_callback)
For more example, please see :ref:`api_guide_high_level_api`.
Args:
train_func(callable): A function which will return loss. The loss must be a scalar.
