我试图在我的 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：

>>> 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:

    from qhull import *

我认为问题出在 scipy 的空间上。这是因为当我这样做时

>>> from scipy import spatial

我得到了与 Scikit-learn 相同的错误。

请帮忙。谢谢你。

编辑：新错误。

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)

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

我今天在 OS X El Capitan 上遇到了这个问题。不幸的是，重新安装/安装不起作用，因为问题最终是 OS X 原生的 numpy 安装优于 pip 安装的安装。

我能够按照以下指南解决此问题：https ://apple.stackexchange.com/a/223163

特别是，我使用修复 python 路径的方法来更喜欢 pip 库而不是 OS X 本地库：

创建一个名为fix_mac_path.pthin的文件，/Library/Python/2.7/site-packages其中包含以下内容：

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

我遇到了完全相同的问题。我设法通过从http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn安装 64 位 Windows 的 Windows 二进制文件来使其工作。希望这对你有用
