安装anaconda后，在ipython里导入某些模块的时候报错
UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured. Please install mkl-service package
解决方法：
先配置三个环境变量，缺一不可
D:\Anaconda3
D:\Anaconda3\Scripts
D:\Anaconda3\Library\bin
将D:\Anaconda3\Library\bin下
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
以上两个文件复制到
D:\Anaconda3\DLLs
问题解决
完成上面步骤后重启vscode
PS E:\mydoc\sync_pc_home_work\pyfile> conda activate base
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.
To initialize your shell, run
$ conda init <SHELL_NAME>
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'.
接着

powershell会报无法加载脚本的错误，
然后会报无法运行脚本错误

下面这个对我无效
直接原因：powershell和cmd是不一样的，在cmd输入conda activate xxx可以看到前面的base环境变成相应的xxx环境，而在powershell中却不会。
直接说解决方法：打开powershell输入conda init即可解决，无需添加环境变量，无需改动powershell，代价是每次打开powershell都将花几百毫秒加载文件
我使用的是vscode，终端默认powershell，如果是cmd就完全不会有这个提示，所以这个报错的原因在于powershell的缺陷
