linux之conda环境安装全过程

这篇文章主要介绍了linux之conda环境安装全过程，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

下载conda

选择自己想要的版本下载，如我选的是这个，下完之后挪到linux服务器中

或者，我们可以复制下载的链接，直接在服务器上下载，如：

wget -c https://repo.anaconda.com/archive/Anaconda3-2021.05-Linux-x86_64.sh

安装conda

在conda文件的统计目录下输入命令安装，一路回车，直到他要求输入yes

bash Anaconda3-2021.05-Linux-x86_64.sh

配置环境变量,这里的export PATH填的是conda的bin文件地址，我是安装在家目录的所以是这样，前面一个命令是添加环境变量，后者是刷新bashrc

export PATH=~/anaconda3/bin:$PATHsource ~/.bashrc

然后conda version要是正常就安装成功了

注：三种配置环境变量的方法

修改/etc/profile
修改.bashrc
直接在shell下用export命令修改

镜像源配置

conda配置

vim ~/.condarc

然后配置镜像，如

pip配置

mkdir ~/.pip cd ~/.pip/ vim pip.conf

然后配置镜像，如：

[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com

常用命令

# 创建虚拟环境 conda create -n name python==3.7 # 激活环境 conda activate name # 退出环境 conda deactivate # 查看虚拟环境 conda info --envs # 删除虚拟环境 conda remove -n name --all # 删除所有的安装包及cache(索引缓存、锁定文件、未使用过的包和tar包) conda clean -y --all # 删除pip的缓存 rm -rf ~/.cache/pip

安装pytorch：

按照官网来，选好自己的配置之后直接复制就是了
