TensorFlow学习笔记：1、TensorFlow快速下载与安装

1.1 安装python-pip

[root@node1 ~]# yum install -y python-pip

1.2 安装TensorFlow

直接执行命令pip install tensorflow即可安装TensorFlow。

[root@node1 ~]# pip install tensorflow

由于从国外网站下载相关软件包，速度较慢。可以指定国内源进行下载安装。此处通过-i选项指定清华源https://pypi.tuna.tsinghua.edu.cn/simple。
执行命令：pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow

[root@node1 ~]# pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow
