python - 无法导入Scikit-Learn

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

sudo python2.7 setup.py install

然后，我将目录更改为home并启动python2.7 shell。在导入sklearn时，我得到了:

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

    from ckdtree import *

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

    from qhull import *

我认为问题出在scipy的空间。这是因为当我做

>>> from scipy import spatial

我收到与Scikit-learn相同的错误。

请帮忙。
谢谢你。

编辑:新错误。

最佳答案

我不确定，但是根据this的说法，当针对特定版本(或特定平台)编译依赖于numpy的程序包，然后将该程序包安装在不同的环境中时，会发生错误。您是如何安装这两个软件包的？ (numpy和scipy)

我建议先卸载这两个软件，然后再重新安装SciPy(using pip或from source)。
