Linux无root权限conda初始化

pre { overflow-y: auto; max-height: 400px }
img { max-width: 500px; max-height: 300px }

1. 给anaconda文件写入权限

sudo chmod a+w .conda

如果没有权限则会在创建环境时报以下错误

NoWritableEnvsDirError: No writeable envs directories configured.
  - /home/ubuntu/.conda/envs
  - /usr/local/miniconda3

2. 创建环境

  conda create -n myenv
  # 若服务器已经预装了相关的环境（比如某些市场镜像已预装了tensorflow或PyTorch），则可以直接克隆环境
  conda create -n myenv --clone base

3. 激活环境

  conda activate myenv

如果出现以下报错:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

则说明当前的shell没有配置使用conda activate，需要初始化

先获取当前shell类型

  echo $0

再初始化shell

  conda init <shell type>

然后重启shell之后再conda activate即可。
