PaddlePaddle支持使用pip快速安装目前支持CentOS 6以上, Ubuntu 14.04以及MacOS 10.12并安装有Python2.7。
执行下面的命令完成快速安装:
.. code-block:: bash
pip install paddlepaddle
如果需要安装支持GPU的版本需要执行
.. code-block:: bash
pip install paddlepaddle-gpu
更详细的安装和编译方法参考:

创建一个 housing.py 并粘贴此Python代码
.. code-block:: python
import paddle.v2 as paddle
# Initialize PaddlePaddle.
paddle.init(use_gpu=False, trainer_count=1)
# Configure the neural network.
x = paddle.layer.data(name='x', type=paddle.data_type.dense_vector(13))
y_predict = paddle.layer.fc(input=x, size=1, act=paddle.activation.Linear())
# Infer using provided test data.
probs = paddle.infer(
output_layer=y_predict,
parameters=paddle.dataset.uci_housing.model(),
input=[item for item in paddle.dataset.uci_housing.test()()])
for i in xrange(len(probs)):
print 'Predicted price: ${:,.2f}'.format(probs[i][0] * 1000)
执行 :code:`python housing.py` 瞧! 它应该打印出预测住房数据的清单。
