在 Windows 上安装 Scikit-Learn

Question

我正在尝试在我的 Windows 8 64 位计算机上安装 Scikit-Learn：

pip install -U scikit-learn

我收到以下错误，

F:\path\python-2.7.10.amd64>pip install -U scikit-learn

请注意： 在做了一些初步的谷歌搜索之后，我发现我必须以管理员身份启动 CMD，我这样做了，但仍然遇到这个错误。

请提出一些解决方案。

Answer 1

查看多个答案后，我决定卸载 Anaconda 并重新安装。这解决了问题。

我还发现了 Win-Python，不知为何，我发现它比 Anaconda更方便。

谢谢。 :)
