無法導入Scikit-Learn

Question

我試圖在我的Linux Mint 12上安裝scikit-learn，但失敗了。我從http://pypi.python.org/pypi/scikit-learn/下載的軟件包，並安裝了

sudo python2.7 setup.py install 

然後我改變了目錄，對家庭，開始python2.7外殼。在進口sklearn我得到：

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

    from ckdtree import *

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

我認爲問題是與scipy的空間。這是因爲當我做

>>> from scipy import spatial 

我得到同樣的錯誤，我得到的Scikit學習。

請幫忙。 謝謝。

編輯：新錯誤。

Answer 1

我真的不知道，但是當這取決於numpy的包被編譯針對特定版本（或一個特定的平臺）根據this恰巧錯誤，然後該程序包安裝在不同的環境。你是如何安裝這兩個軟件包的？ （numpy和scipy）

我建議卸載並重新安裝SciPy，using pip或from source。

Answer 2

我有完全相同的問題。我設法通過安裝來自http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn的64位窗口的windows二進制文件來工作。希望這對你有用

Answer 3

我今天在OS X El Capitan遇到了這個問題。不幸的是，重新安裝/安裝不起作用，因爲問題最終導致OS X原生的numpy安裝優於pip安裝的安裝。

我能夠通過遵循指導來解決這個：https://apple.stackexchange.com/a/223163

特別是，我用固定蟒蛇路徑，通過OS X機庫喜歡點子庫的方法：

創建一個文件在/Library/Python/2.7/site-packages稱爲fix_mac_path.pth具有以下：

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
