Original error was: DLL load failed while importing _multiarray_umath: 找不到指定的模块

查了一些博客说配置anaconda的环境变量，可是环境变量我已经配置好了，不可能为每一个Conda中的Python环境创建一个变量，这种解决方式不可行；

由于我运行代码是在VSCode中运行的，其默认调用的终端为Windows自带的PowerShell，因此我在自带的PowerShell中运行Conda环境，并激活所要使用的Python环境，使用之后并没有出现命令行之前显示(base)等环境名称的字样，使用python命令不会进入Python的Shell，说明PowerShell出现了问题！

查阅资料发现，PowerShell目前只支持Conda 4.6版本，而我的版本较高为：

2 解决

安装最新的PowerShell，参考微软官方教程：https://learn.microsoft.com/zh-cn/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.3

最新版PowerShell可以正常激活环境，并在VSCode中使用
