conda常用命令

1.创建、启动虚拟环境

conda create -n  env_name python=3.7 
conda activate env_name

如果出现如下类似错误：

nvalidArchiveError(‘Error with archive /usr/local/Anaconda3/pkgs/sqlite-3.36.0-hc218d9a_0stdo5ow0/info-sqlite-3.36.0-hc218d9a_0.tar.zst. You probably need to delete and re-download or re-create this file. Message from libarchive was:\n\nCould not unlink’)
————————————————

解决办法：
找到对应的pkgs包，赋权限777即可

sudo chmod -R 777 /usr/local/Anaconda3/pkgs/

2.查看虚拟环境用户

conda env list

3.查看安装软件版本

conda list

conda 安装torch等

参考：https://pytorch.org/get-started/previous-versions/

# 先创建虚拟账户然后
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=10.2 -c pytorch

默认国外源，安装太慢，修改源：
将以上配置文件写在~/.condarc中
vim ~/.condarc
