本文主要包括如下几个部分:

*  docker 安装
 *  pip安装
 *  编译安装
 *  问题
 *  参考文献

--------------------

## 1. docker安装 ##

下载官方的镜像，即可使用。不过不推荐，因为这个Tensorflow的模块是在Docker内的，也就是你编译的时候，需要进入Docker镜像的内部进行使用。也就是`import tensorflow as tf`命令在你的Docker外是无法生效的。使用IDEA这样的调试工具调试的时候，会略微有点蛋疼。

但是，学习Tensorflow语法的话可以使用相对应的Jyter这个工具平台进行学习，非常方便。

分享一个很好的TensorFlow的Docker镜像和Docker仓库:

*  github 项目: `https://github.com/caicloud/tensorflow-tutorial`
 *  docker 仓库 `docker pull cargo.caicloud.io/tensorflow/tensorflow:0.12.0`
 *  `启动 docker run - it cargo.caicloud.io/tensorflow/tensorflow:0.12.0 -p 8888:8888 -p 6066:6066`
 *  8888为Jupyter编辑器,docker logs 会看到如下的内容,里面包含密码。访问[http://localhost:8888][http_localhost_8888]即可进入Jupyter编辑器。6066为TensorBoard。

[root@rhel6 ~]# docker logs 45fd0affc965

    [I 03:19:24.339 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

--------------------

## 2. pip安装 ##

使用pip前，先确定安装了python。  
在命令行输入`python`/`python3`，即可判断你是否全局配置了python程序。

MAC OSX系统不推荐使用官方自带的Python2.7.3程序，因为那边有很多的程序是被写保护的。

Ubuntu/Linux 
    
    # 仅使用 CPU 的版本
    $ pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl
    
    # 开启 GPU 支持的版本 (安装该版本的前提是已经安装了 CUDA sdk)
    $ pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl
    
    Mac OS X 
    
    # 当前版本只支持 CPU
    $ pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl
    
    Docker
    
    $ docker run -it b.gcr.io/tensorflow/tensorflow

--------------------

## 3. 编译安装 ##

不推荐

--------------------

## 4. 问题 ##

使用pip安装基本没有什么问题，但是需要注意的是。千万不要使用Mac自带的python，那个地方是写保护的。

报错信息如下:

        DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

解决办法: `brew install python`，使用新的python即可。
