Tensorflow安装
首先打开Tensorflow官方下载合适的版本：https://www.tensorflow.org/install/
官方可以使用四种方式安装：
- virtualenv
- "native" pip
- Docker
- 使用源码安装
本文使用pip安装，需要准备好pip版本。另外请注意使用的是CPU还是GPU版本。GPU版本会快很多。
Tensorflow模板需要Python的版本是：
- Python 2.7
- Python 3.3+
我的Mac使用的是python 2.7版本。
另外需要关闭Mac的的System Integrity Protection的问题，解决的办法是关闭保护SIP，以及允许安装第三方的软件。
关闭SIP
- 重启电脑，电脑启动的时候按住command+R；
- 等画面上显示苹果logo的时候之后，你会看到顶部菜单「实用工具」，选择子菜单"终端"；
- 然后终端就打开了，你直接输入 csrutil disable ，输完之后重启
首先检查pip的版本。
bogon:~ geguo$ pip -V #注意是大写的V
pip 6.0.3 from /Library/Python/2.7/site-packages (python 2.7)
官网推荐使用高版本的pip，首先升级pip
sudo easy_install --upgrade pip
sudo easy_install --upgrade six
再次检查版本
pip -V
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)
安装 TensorFlow
安装Tensorflow的过程非常简单。
pip install tensorflow # Python 2.7; CPU support

验证安装
安装完毕后，我们需要来验证是否安装无误。
$python
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
如果python输入以下内容，就说明安装正确了。
Hello, TensorFlow!
