一、安装anaconda

tensorflow是基于Python脚本语言的，因此需要安装python, 当然还需要安装numpy、scipy、six、matplotlib等几十个扩展包。如果一个个安装，装到啥时候去？（我曾经光安装scipy就装了一天。。。）

不过现在有了集成环境anaconda，安装就方便了。python的大部分扩展包, 都集成在anaconda里面了，因此只需要装这一个东西就行了。

先到https://www.continuum.io/downloads 下载anaconda, 现在的版本有python2.7版本和python3.5版本，下载好对应版本、对应系统的anaconda，它实际上是一个sh脚本文件，大约300M-400M左右。

$ bash Anaconda3-4.4.0-Linux-x86_64.sh

if finish install,please close terminal.

二、安装tensorflow

先在终端执行：

anaconda search -t conda tensorflow

搜索一下有哪些tensorflow安装包，通过查看版本，选择最高的版本安装。

因此，执行下面代码来查看详细信息：

anaconda show jjh_cio_testing/tensorflow

它就会告诉你，怎么来安装这个包,在终端执行：

To install this package with conda run:
conda install --channel https://conda.anaconda.org/jjh_cio_testing tensorflow

然后输入"y"，进行安装。

三、调试

安装成功与否，我们可以测试一下。

在终端输入python，进入python编译环境，然后输入：

import tensorflow as tf

引包tensorflow包，如果没有报错，则安装成功，否则就有问题。

然后可以输入

tf.__version__tf.__path__

查看tensorflow的安装版本和安装路径（左右各两根下横线）。
