貌似因为mac os Sierra默认不支持matplotlib 解决方法如下： 安装matplotlib pip install matplotlib 报错 * The following required packages can not be built:Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-8UvQcW/matplotlib

解决方法，先执行 sudo apt-get install libfreetype6-dev pkg-config 再安装matplotlib pip install matplotlib

最后执行 cd data && python prepare_data.py 提示 housing.data housing.test.npy housing.train.npy prepare_data.py test.list train.lis

Done.
