Eu tentei instalar scikit-learn no meu Linux Mint 12, mas falhou. Eu baixei o pacote dehttp://pypi.python.org/pypi/scikit-learn/ e instalado com

sudo python2.7 setup.py install

Então mudei o diretório para home e iniciei o python2.7 shell. Importando sklearn eu consegui:

>>> 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:

Eu acho que o problema é com o scypys espacial. Isso é porque quando eu faço

>>> from scipy import spatial

Eu recebo o mesmo erro que recebo pelo Scikit-learn.

Por favor ajude. Obrigado.

EDIT: novo erro.
