所以我一直在尝试机器学习，我发现本教程告诉我要获得以下python软件包：
现在的事情是，只会安装numpy和pandas。其他人给我这些错误，它们很长，我听不懂
C:\Users>python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose sklearn
'python' is not recognized as an internal or external command,
operable program or batch file.

在使用Python时，请考虑使用Anaconda来管理软件包。链接：https://docs.conda.io/projects/conda/en/latest/user-guide/install/windows.html
尽管学习一种新工具似乎令人生畏，但请相信我，这是正确的方法，将大大简化您的生活。
