无法导入Scikit-Learn
我试图在我的Linux Mint12上安装scikit-learn，但是失败了。我从http://pypi.python.org/pypi/scikit-learn/下载了这个包，并与
sudo python2.7 setup.py install然后，我将目录更改为home并启动python2.7shell。在导入sklearn时，我得到了：
>>> import sklearn

from qhull import *我想问题出在scipy的空间上。这是因为当我这样做时
>>> from scipy import spatial我得到了与Scikit-learn相同的错误。
请帮帮忙。谢谢。
编辑:新错误。
>>> import sklearn

我不是很确定，但根据this的说法，当依赖于numpy的包针对特定版本(或特定平台)进行编译，然后将该包安装在不同的环境中时，就会发生错误。您是如何安装这两个包的？(numpy和scipy)
我建议先卸载这两个版本，然后再重新安装SciPy，using pip或from source。

我今天在OS X El Capitan上遇到了这个问题。不幸的是，重新安装/安装不起作用，因为问题最终是OS原生的numpy安装比pip安装的更受欢迎。
我能够通过遵循下面的指南解决这个问题：https://apple.stackexchange.com/a/223163
特别是，我使用了修复python路径的方法，以便优先使用pip库而不是OS X本地库：
在/Library/Python/2.7/site-packages中创建一个名为fix_mac_path.pth的文件，该文件包含以下内容：
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

我也遇到了同样的问题。通过从http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn安装64位windows的windows二进制文件，我设法使其正常工作。希望这对你有用
