第一步：安装pip工具

sudo apt-get install python-pip python-dev

第二步：安装tensorflow-cpu版

#安装cpu版0.9.0版本sudo pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0-cp27-none-linux_x86_64.whl#安装cpu版0.5.0版本：sudo pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl#安装gpu版0.9.0sudo pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.9.0-cp27-none-linux_x86_64.whl#安装gpu版0.5.0版本：sudo pip install https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

第三步：打开sublime-text3 使用SFTP连接ubuntu系统出现如下错误

The SSH host key has changed. This could indicate a potential security breach, or that the domain you are connecting to recently moved servers.
If you are confident this is not a security breach you can delete the old host key and try again.
1. Win XP: Start > Run > regedit.exe
Win Vista/7: Start > regedit
2. Expand to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\SshHostKeys and delete the entry including @22:10.0.83.202
打开windows7下按以上步骤打开并删除相应记录

第四步：linux上测试tensor测试文件

test.py

import numpyimport tensorflow as tfhello = tf.constant("hello,tensorflow")sess = tf.Session()print sess.run(hello)a = tf.constant(10)b = tf.constant(20)print sess.run(a+b)

linux安装anaconda2 下载地址：https://repo.continuum.io/archive/index.html 安装到/usr/local/anaconda2中
或者指令：sudo apt-get install python-dev 软件后在安装numpy 指令：sudo apt-get install python-numpy
tensorflow的安装目录：/usr/local/lib/python2.7/dist-packages/tensorflow
