Centos7.3下安装TensorFlow最新版本，基于python2.7.5的，没有编译TensorFlow的源码，这样不好啊，没有编译源码，没有
经过，优化，TensorFlow跑起来挺慢，而且会有一些警告。但是这样安装快。先装上再说吧。
人工智能第一步啊：
前奏：如果想装高版本的python，可以这样

注：此时安装的为最新版本的TensorFlow1.3.0，若想使用旧版本，可以通过如下指令安装：
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-x.x.x-cp27-none-linux_x86_64.whl
x.x.x是你选择的版本号，如0.6.0、0.8.0、1.0.0……
可以通过pip list 查看已经装过的TensorFlow的版本。
5.安装好TensorFlow，可以进行简单的测试，看看是否真的安装成功。

看到此，恭喜你。你已经成功的在CentOS7上面部署了TensorFlow，接下来，开始愉快的玩耍吧！！！对于此警告，是因为通过pip直接安装的包没有针对本地环境进行优化，其不影响代码的执行，可以不用管。要是你有强迫症，非要进行处理，可自行设置一下TensorFlow的log显示等级（默认为0–显示所有日志，取值1-3时显示内容递减），快速的方式是在程序中加入如下代码：
import os
os.environ[‘TF_CPP_MIN_LOG_LEVEL’]=’2’
不过在下次启动时，当前的配置会失效，警告又会出现。一劳永逸的办法就是花个十几二十分钟编译一个健全的TensorFlow。具体的流程会在后续的博客中介绍，敬请期待！！！
