导入scikit学习模块时出错

Question

我正在尝试从集群模块调用函数，如下所示：

import sklearn
db = sklearn.cluster.DBSCAN()

我收到以下错误：

AttributeError: 'module' object has no attribute 'cluster'

在IPython中，制表符补全似乎可以访问基本，克隆，外部，re，setup_module，sys和警告模块。sklearn目录中没有其他（包括群集）。

遵循以下pbu的建议并使用

from sklearn import cluster

我得到：

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from sklearn import cluster
  File "C:\Python34\lib\site-packages\sklearn\cluster\__init__.py", line 6, in <module>

    from . import _iterative
ImportError: DLL load failed: The specified module could not be found.

我在Windows上使用Python 3.4，scikit-learn 0.16.1。

问题是scipy /
numpy安装。我一直在使用http://www.lfd.uci.edu/~gohlke/pythonlibs/中的（通常很出色！）非官方安装程序。从那里卸载/重新安装没有什么区别，但是使用官方安装程序（从http://www.scipy.org/install.html链接）进行安装就可以了。
