pythroch abaconda 安装 cuda、版本确定、pytorch 安装

一、简述

公司有一个深度学习的项目，身上也没有其他项目，恰好乘着个机会学一下pytorch  和YOLOv8.

1、下载abaconda   

https://repo.anaconda.com/archive/

2、安装

 环境变量要✔

其他一直下一步

3、测试

==> WARNING: A newer version of conda exists. <==
  current version: 23.1.0
  latest version: 23.11.0

Please update conda by running

    $ conda update -n base -c defaults conda

Or to minimize the number of packages updated during conda update use

     conda install conda=23.11.0

二、 安装cuda

查看cuda 对应的版本

下载cuda 

检查：nvcc -V 

三、安装pytorch 

清华  下载路径

https://download.pytorch.org/whl/torch_stable.html
