rocky linux 安装 tensorflow

到rockylinux的网站下载安装镜像，

原来以为被某博客误导点击Minimal ISO的镜像，其实Minimal ISO是服务器的安装镜像，差不多2G的大小，将错就错，就用Minimal的ISO镜像安装，感觉rocky linux9的安装过程很慢，比Euler安装时慢很多，安装之后发现安装的vmware有5.7G多的，庆幸当时下载的是Minimal的安装包，虽然没有桌面软件，以后可以选择适用的桌面再安装，其它的使用方法跟centos，都懂的。

rocky linux 安装后得设置 SSH的登陆模式 yes   ，否则 不能使用SSH软件来控制虚拟机里的

python3 --version

先安装 pip

sudo dnf install python3-pip

再用pip --version 查询 发现pip

[root@localhost bin]# pip --version
pip 21.2.3 from /usr/lib/python3.9/site-packages/pip (python 3.9)
发现pip不是最新的，也不按某些教程，非得将pip update到最新的版本，就
先测试下该版本是否能顺利安装tensorflow

[root@localhost tensorFlow]# whereis pip
pip: /usr/bin/pip

接着安装tensorflow先

[root@localhost opt]# mkdir myproject_tensorflow

进入到建立的路径 cd myproject_tensorflow/
再使用以下命令
[root@localhost myproject_tensorflow]# python3 -m venv venv
[root@localhost myproject_tensorflow]# ls
venv
[root@localhost myproject_tensorflow]# source venv/bin/activate

再安装某教程
[root@localhost myproject_tensorflow]# pip install tensorflow=2.2
结果少了个等号，其实是 ==就行，那么算啦

再用原来教程的方法

(venv) [root@localhost myproject_tensorflow]# pip install tensorflow

直接就开始安装tensorflow-2.17的软件，不过速度真的很慢，建议以后安装使用国内的镜像源的方法来安装

Downloading tensorflow-2.17.0-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl (601.3 MB)

国外网站太慢，直接到国内的以下网址去下载镜像

https://pypi.tuna.tsinghua.edu.cn/simple/tensorflow/

 https://pypi.tuna.tsinghua.edu.cn/simple

然后将下载的tensoflow 传到linux的某个位置，再去到相应目录使用以下命令安装

 pip install tensorflow-2.17.0-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
以上命令必须下载相应的安装包，不同的安装包也得更改以上命令
