24.install  anaconda

down from Free Download | Anaconda . then install

bash Anaconda3-2023.03-1-Linux-x86_64.sh 

how to init (self)

source anaconda3/bin/activate

25.config anaconda [vim ~/.bashrc]

1.  
   export PTAH=$PATH:/home/beta/anaconda3/bin
2.  
   # init conda.sh
3.  
   . /home/beta/anaconda3/etc/profile.d/conda.sh
4.  
   alias in_base='conda activate base'
5.  
   alias out_base='conda deactivate'

一、创建虚拟环境

conda  create  --name  env_name

conda  create  --name  env_name python=3.5 # 创建指定python版本

conda  create  --name  env_name python=3.5 numpy scipy # 创建指定python版本下包含某些包

二、激活/使用/进入某个虚拟环境

activate  env_name

三、退出当前环境

deactivate

四、复制某个虚拟环境

conda  create  --name  new_env_name  --clone  old_env_name

五、删除某个环境

conda  remove  --name  env_name  --all

六、查看当前所有环境

conda  info  --envs   或者  conda  env  list

七、查看当前虚拟环境下的所有安装包

conda  list  需进入该虚拟环境

conda  list  -n  env_name

八、安装或卸载包(进入虚拟环境之后）

conda  install  xxx

conda  install  xxx=版本号  # 指定版本号

conda  install  xxx -i 源名称或链接 # 指定下载源
