在Windows命令行中利用Conda高效管理虚拟环境的创建与删除

Windows在命令行中使用conda命令创建删除虚拟环境

1.查看系统现有的conda环境&＃xff1a;conda env list

C:\Users\Administrator>conda env list

# conda environments:

#

base * D:\program files\Anaconda3

C:\Users\Administrator>

2.创建一个名为python37&＃xff0c;Python版本为3.7的conda虚拟环境&＃xff1a;conda create -n python37 python&＃61;3.7

出现下面的情况输入 y(是否安装以下包)

C:\Users\Administrator>conda env list

# conda environments:

#

python37 D:\program files\Anaconda3\envs\python37

C:\Users\Administrator>

3.进入名为python37的环境&＃xff1a;activate python37

C:\Users\Administrator>activate python37

(python37) C:\Users\Administrator>

4.搜索想要安装的包的所有版本(使用tensorflow包举例)&＃xff1a;

(python37) C:\Users\Administrator>conda search tensorflow

5.安装包的时候不加版本号默认安装包的最新版本&＃xff1a;conda install tensorflow

这里安装tensorflow的1.14.0版本&＃xff1a;conda install tensorflow&＃61;&＃61;1.14.0

(python37) C:\Users\Administrator>conda install tensorflow&＃61;&＃61;1.14.0
