CentOS7服务器上部署深度/机器学习环境推荐首选anaconda3，亲测~~ 因为可以创建不同的环境版本或虚拟环境

CentOS7服务器安装anaconda3后，CentOS7服务器开启后自动将anaconda3自身的root(或base)环境开启。
用Xshell打开CentOS7服务器后，可以看见 (base)

查看环境，发现anaconda3自身的root(或base)环境处于活动状态 ============== 默认开机启动（在指定的用户下）
(base) [jiangshan@localhost ~]$ conda info -e
# conda environments:
#
base * /home/jiangshan/anaconda3
（ * 代表活动状态）
===================试验=======================================================
(base) [jiangshan@localhost ~]$ source deactivate
DeprecationWarning: 'source deactivate' is deprecated. Use 'conda deactivate'.

# TenssorFlow目前还不支持Python 3.7，使用Anaconda3创建Python 3.6虚拟环境
# 创建基于python 3.6 的tensorflow环境：
(base) [jiangshan@localhost ~]$ conda create --name tensorflow python=3.6

查看创建的tensorflow环境
(base) [jiangshan@localhost ~]$ conda info -e
# conda environments:
#
base * /home/jiangshan/anaconda3
tensorflow /home/jiangshan/anaconda3/envs/tensorflow

已经创建tensorflow环境，暂未进入激活
激活 tensorflow
(base) [jiangshan@localhost ~]$ source activate tensorflow

查看已激活的tensorflow环境
(tensorflow) [jiangshan@localhost ~]$ conda info -e
# conda environments:
#
base /home/jiangshan/anaconda3
tensorflow * /home/jiangshan/anaconda3/envs/tensorflow 【有 * 号】

在 tensorflow环境安装 tensorflow
(tensorflow) [jiangshan@localhost ~]$ conda install tensorflow
