$ conda --version
conda 23.11.0
使用conda安装pytorch(CPU版本)
注意:默认conda安装pytorch的是cpu版本,如需要安装GPU版本的,注意直接看后面
创建一个新conda环境
$ conda create -n myPyt
新创建的环境不包含任何依赖可以使用conda list
查看一下
开始安装pytorch(当然,也可以前面在创建环境的同时,把依赖包一同时安装了)
$ conda install pytorch
为了方便验证同时安装ipython
IPython 是 Python 的原生交互式 shell 的增强版,可以完成许多不同寻常的任务,比如帮助实现并行化计算;主要使用它提供的交互性帮助,比如代码着色、改进了的命令行回调、制表符完成、宏功能以及改进了的交互式帮助
# 激活环境
$ conda activate myPyt
# 安装ipython
$ conda install ipython
验证一下pytorch环境
输入ipython
,进入交互式环境,依次输入如下两条命令import torch
、torch.cuda.is_available()
$ ipython
Python 3.11.7 (main, Dec 15 2023, 18:12:31) [GCC 11.2.0]
Type 'copyright', 'credits' or 'license' for more information
IPython 8.20.0 -- An enhanced Interactive Python. Type '?' for help.
In [1]: import torch
In [2]: torch.cuda.is_available()
Out[2]: False
发现当前的版本是不cpu版本,不支持cuda加速的,我们查看一下依赖

如何安装gpu版本的pytorch呢?我们继续
我们查看一下pytorch可安装的版本

列中,有点的cpu
有的是gpu
,那么如何安装时指定安装带gpu表示的版本的呢?
我们只需制定版本号的同时,指定build即可

安装时,从提示安装的依赖我们可以看出,这个版本确实带上了cuda相关包cudatoolkit
、cudnn
,这次安装显然时间长了很多,包的大小也近2G
安装完成后,我们再次确认一下cuda加速是否可用;
同样,我们先安装一个ipython
$ conda install ipython
进入ipython
后,依次执行如下代码import torch
、torch.cuda.is_available()
$ ipython
Python 3.9.18 (main, Sep 11 2023, 13:41:44)

这次cuda可以正常工作,到此完成gpu版本的pytorch安装
当然不是采用conda安装的话,希望自己手鲁,从nvidia驱动、cuda、cudnn这些库开始手动一个个安装好后,最后再安装pytorch也是可以的;关于pytorch手动安装方式,这里给出官方地址,点这里文章来源:https://www.toymoban.com/news/detail-828511.html
最后再安装个jupyter工具
conda install jupyter
启动命令jupyter-notebook
