导入错误：DLL 加载失败：找不到指定的模块（sklearn）

Question

I installed numpy, scipy and scikit-learn in Python 3.5. When I run my program, I get this error.

Traceback (most recent call last):

Answer 1

I have the same problem too, after days of searching and reinstalling almost every thing. I found out the answer:

Step 1: Uninstall scipy and numpy

Step 2: Dowload numpy+mkl( the package name is numpy+mkl, not numpy package and mkl package) and scipy from this page as armatita mentioned

Step3: Install numpy+mkl first and scipy after that

Good luck to you

Answer 2

It actually requires numpy + mkl . But it's difficult to say if that is the problem with your distribution.

My advice is that you use one of the available distributions that already bring those libraries. I recommend WinPython , but I also heard good things about Anaconda .

It's easy to install other packages with WinPython using:

Unofficial Windows Binaries for Python Extension Packages

By Christoph Gohlke .

If you really want to solve that issue with your current distribution you'll have to provide more information such as versions that you installed, previous modules installed, and how you installed them.

Answer 3

试试 Anaconda，它会解决你的问题。

Answer 4

卸载并重新安装 numpy 和 scipy，这为我解决了问题。
