安装和测试过程：

#CentOS7 Root
su root

#安装依赖
yum install python python-devel -y
pip install --upgrade pip --default-timeout 600
#安装paddlepaddle 
pip uninstall paddlepaddle
pip install paddlepaddle --default-timeout 600

#创建测试脚本
mkdir /home/work/paddle && cd /home/work/paddle
vim housing.py

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)

#测试
python housing.py
