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]
export PTAH=$PATH:/home/beta/anaconda3/bin
# init conda.sh
. /home/beta/anaconda3/etc/profile.d/conda.sh
alias in_base='conda activate base'
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
conda uninstall xxx ———————————————— 版权声明：本文为CSDN博主「高启强668」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/zhognsc08/article/details/122735811
