CentOS 7.6安装Tensor flow 1.13 GPU版本（RTX2070）

Tensorflow官网推荐使用的操作系统是Ubuntu 16.04或者18.04，我个人比较喜欢CentOS，所以就选择在CentOS 7上安装。

1、CentOS 7.6的安装（当前最新的64位版本）

      安装的时候注意要安装开发环境：gcc和linux kernel源代码的.h文件在后面安装GPU的驱动要用

2、确定与Tensorflow对应的cuda、cuDNN版本

    网址：https://tensorflow.google.cn/install/source， 这个是官网，信息比较权威（百度出来的内容很多都不准确，而且比较老。毕竟RTX2070是比较新的显卡）

    从官网的信息可知在LINUX平台上，有如下的对应关系：

3、下载并安装CUDA 10和cuDNN

     CUDA: https://developer.nvidia.com/cuda-10.0-download-archive?target_os=Linux&target_arch=x86_64&target_distro=CentOS&target_version=7&target_type=runfilelocal

     cuDNN: https://developer.nvidia.com/rdp/cudnn-archive  Download cuDNN v7.4.2 (Dec 14, 2018), for CUDA 10.0

     说明：1）、不需要另外安装RTX2070的驱动，已经包含在CUDA里面了。

                2）、安装驱动的时候需要把X window关闭：一般就ps -eaf|grep X，找出来直接kill

4、Tensorflow_gpu安装

     根据对应关系，只能用python 3.6。 我习惯用anaconda，在这里犯了不少错误，试了好几个版本，最后确定3.6的最新版本是Anaconda3-5.2.0-Linux-x86_64.sh     tensorfow最新的1.13 gpu版本下载：https://files.pythonhosted.org/packages/7b/b1/0ad4ae02e17ddd62109cd54c291e311c4b5fd09b4d0678d3d6ce4159b0f0/tensorflow_gpu-1.13.1-cp36-cp36m-manylinux1_x86_64.whl

5、安装完成后，运行hello
