python - 无法导入 Scikit-Learn

Question

我尝试在我的 Linux Mint 12 上安装 scikit-learn 但失败了。我从 http://pypi.python.org/pypi/scikit-learn/ 下载了这个包并安装

sudo python2.7 setup.py install

然后我将目录更改为 home 并启动了 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: 
numpy.dtype size changed, may indicate binary incompatibility
    from ckdtree import *

    from ckdtree import *

    from qhull import *
/usr/lib/python2.7/dist-packages/scipy/spatial/__init__.py:8: RuntimeWarning:  
numpy.ufunc size changed, may indicate binary incompatibility
    from qhull import *

我认为问题在于 scipy 的空间。这是因为当我这样做的时候

>>> from scipy import spatial

我遇到了与 Scikit-learn 相同的错误。

请帮忙。谢谢你。

编辑:新错误。

我不太确定，但根据 this当针对特定版本(或特定平台)编译依赖于 numpy 的包，然后将该包安装在不同的环境中时，就会发生该错误。你是怎么安装这两个包的？ (numpy 和 scipy)

我建议卸载两者然后重新安装 SciPy，要么 using pip或 from source .
