'From/import' 不是内部或外部命令，也不是可运行的程序或批处理文件 [英] 'From/import' is not recognized as an internal or external command, operable program or batch file

问题描述

我在从 scikit-learn 导入机器学习算法时遇到问题.我已经安装了它，但是每当我输入例如from sklearn.naive_bayes import GaussianNB"时，它都会说'from'不被识别为内部或外部命令、可运行的程序或批处理文件.我在 Windows 10 上使用 Anaconda.这是兼容性问题吗?我错过了什么吗?Idk 我还是 Python 的新手，所以我感到迷茫.谢谢

I'm having trouble importing Machine Learning algorithms from scikit-learn. I have it installed but whenever I type for example "from sklearn.naive_bayes import GaussianNB" it says " 'from' is not recognized as an internal or external command, operable program or batch file. I'm using Anaconda on Windows 10. Is it compatibility issue? Am I missing something? Idk I'm still new to Python so I feel lost. Thanks

推荐答案

这需要在 Python REPL 中运行，而不是在命令行中运行.在输入 Python 语句之前一定要开始一个.

That needs to be run in the Python REPL, not at a command line. Be sure to start one before typing Python statements.
