无法导入Scikit-Learn [英] Cannot import Scikit-Learn

问题描述

我尝试在Linux Mint 12上安装scikit-learn，但失败了.我从 http://pypi.python.org/pypi/scikit-learn/下载了该软件包并安装了与

I tried to install scikit-learn on my Linux Mint 12 but failed. I downloaded the package from http://pypi.python.org/pypi/scikit-learn/ and installed with

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:

I then changed the directory to home and started python2.7 shell. On importing sklearn I got:

>>> 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 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 *

我认为问题出在scipy的空间.这是因为当我这样做

I think the problem is with scipy's spatial. This is because when I do

>>> from scipy import spatial

我遇到的错误与Scikit学习中的错误相同.

I get the same error that I get for Scikit-learn.

请帮助. 谢谢你.

新错误.

推荐答案

我不确定，但是根据

I'm not really sure, but according to this that error happens when a package that depends on numpy is compiled targeting a specific version (or a specific platform), and that package is then installed in a different environment. How did you install those two packages? (numpy and scipy)

我建议同时使用pip 使用pip 或

I'd suggest uninstalling both and then reinstalling SciPy, either using pip or from source.
