快速开始
========
快速安装
--------
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版本为cpu_avx_openblas
.. code-block:: bash
pip install paddlepaddle
如果需要安装支持GPU的版本cuda8.0_cudnn5_avx_openblas),需要执行:
.. code-block:: bash
pip install paddlepaddle-gpu
更详细的安装和编译方法参考: :ref:`install_steps`
快速使用
--------
创建一个 housing.py 并粘贴此Python代码
.. code-block:: python
import paddle.dataset.uci_housing as uci_housing
import paddle.fluid as fluid
with fluid.scope_guard(fluid.core.Scope()):
# initialize executor with cpu
exe = fluid.Executor(place=fluid.CPUPlace())
# load inference model
[inference_program, feed_target_names,fetch_targets] = \
fluid.io.load_inference_model(uci_housing.fluid_model(), exe)
# run inference
result = exe.run(inference_program,
feed={feed_target_names[0]: uci_housing.predict_reader()},
fetch_list=fetch_targets)
# print predicted price is $12,273.97
print 'Predicted price: ${:,.2f}'.format(result[0][0][0] * 1000)
执行 :code:`python housing.py` 瞧! 它应该打印出预测住房数据的清单。
