导入sklearn时出错

Python版本：3.5.2

我开始学习机器学习和事物…所以我安装了sklearn和其他一些以pip形式出现的软件包.除了sklearn以外,所有其他组件都能够成功安装,因此我下载了车轮并从here开始安装.安装成功,但是当我尝试导入以检查正确安装的顺序时,出现了很多错误：

ImportError: DLL load failed: The specified module could not be found.

代码只是：

import sklearn

我已经检查了下载的车轮包装的正确版本.

我该如何纠正它以及为什么会发生？

解决方法:

以下步骤解决了我的问题：

>卸载numpy,sklearn和scipy.
>从here下载numpy mkl和scipy.
>首先安装numpy mkl,然后安装scipy.
>从pip安装sklearn.
