最近我开始学习深度学习框架Tensorflow，一开始在Windows 平台下的anaconda下安装，由于anaconda安装几次后navigator打开老是出现闪退的问题，所以决定换个Ubuntu下继续折腾tensorflow。本人笔记本没有NVIDIA 显卡，只装的CPU 版本的。而且是在虚拟机下的，下面开始吧。

先安装好Ubuntu 18.04版本的系统（最好是Ubuntu的14.04版本以上），Ubuntu系统已经有了了Python 3.7.7.7，所以不需要再安装Python了。

一、首先更新源为阿里云软件源，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.list1

（3）替换内容后，保存

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

4）更新源列表

sudo apt-get update

二、安装Tensorflow（Python3.6.7/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）

linuxidc@linuxidc:~/linuxidc.com$ sudo pip3 install tensorflow

（3）测试tensorflow
