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

在win10创建了虚拟环境后，用“conda activate 虚拟环境名”，出现如下错误：

CommandNotFoundError: Your shell has not been properly configured to use 'conda deactivate'.
If using 'conda deactivate' from a batch script, change your
invocation to 'CALL conda.bat deactivate'.

To initialize your shell, run

    $ conda init 

Currently supported shells are:
  - bash
  - cmd.exe
  - 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'.

解决方法：
直接输入“activate 虚拟环境名”进入虚拟环境，输入“deactivate 虚拟环境名”退出虚拟环境。
