无法导入Scikit-Learn

Question

我试图在我的Linux Mint 12上安装scikit-learn，但失败了。我从http://pypi.python.org/pypi/scikit-learn/下载的软件包，并安装了

sudo python2.7 setup.py install 

然后我改变了目录，对家庭，开始python2.7外壳。在进口sklearn我得到：

>>> import sklearn 
/usr/lib/python2.7/dist-packages/scipy/spatial/__init__.py:7: RuntimeWarning:

    from ckdtree import *

/usr/lib/python2.7/dist-packages/scipy/spatial/__init__.py:8: RuntimeWarning:

    from qhull import * 

我认为问题是与scipy的空间。这是因为当我做

>>> from scipy import spatial 

我得到同样的错误，我得到的Scikit学习。

请帮忙。 谢谢。

编辑：新错误。

Answer 1

我真的不知道，但是当这取决于numpy的包被编译针对特定版本（或一个特定的平台）根据this恰巧错误，然后该程序包安装在不同的环境。你是如何安装这两个软件包的？ （numpy和scipy）

我建议卸载并重新安装SciPy，using pip或from source。

Answer 2

我有完全相同的问题。我设法通过安装来自http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn的64位窗口的windows二进制文件来工作。希望这对你有用

Answer 3

我今天在OS X El Capitan遇到了这个问题。不幸的是，重新安装/安装不起作用，因为问题最终导致OS X原生的numpy安装优于pip安装的安装。

我能够通过遵循指导来解决这个：https://apple.stackexchange.com/a/223163

特别是，我用固定蟒蛇路径，通过OS X机库喜欢点子库的方法：

创建一个文件在/Library/Python/2.7/site-packages称为fix_mac_path.pth具有以下：

import sys; std_paths=[p for p in sys.path if p.startswith('/System/')]; sys.path=[p for p in sys.path if not p.startswith('/System/')]+std_paths
