Ubuntu下安装Tensorflow(CPU)

Ubuntu下安装Tensorflow(CPU)

一、更新为阿里云软件源，增加下载速度

（1）备份当前也就是默认官方的源列表

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

（2）删除sources.list文件中的列表，删除全部内容

sudo gedit /etc/apt/sources.list

（3）替换内容后，保存

deb http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe

（4）更新源列表

sudo apt-get update

二、安装Tensorflow（Python3.5.2/CPU）

（1）安装Python3的包管理pip

sudo apt-get install python3-pip python3-dev

（2）安装tensorflow

（自动安装相关库numpy、tensorboard、six、protobuf、html5lib、bleach、werkzeug、markdown）

sudo pip3 install tensorflow

（3）测试tensorflow

import tensorflow as tf
a = tf.constant(1)
b = tf.constant(2)
op = a + b
sess = tf.Session()
sess.run(op)
sess.close()
