场景：

ubuntu系统

问题描述：

使用conda activate pytorch想激活虚拟环境pytorch时报错：

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'.

然而，按他的推荐先退出并重启shell再执行conda init后仍无法解决。

原因分析：

未正确退出环境，会导致这样的报错。

解决方法：

运行：

source activate
conda deactivate

就可以成功解决啦！
