Sklearn导入错误.在ubuntu 14.04上没有名为winregg的模块

Question

当我尝试从sklearn导入一个模块时，收到一个错误:

In [1]: import sklearn
In [2]: from sklearn.linear_model import Lasso

ImportError: No module named 'winreg'
In [3]: 

我已经使用官方文档

中解释的命令pip3安装了sklearn。

In [3]: sklearn.__version__
Out[3]: '0.15.1'

winreg应该是一个只适用于windows的模块…我怎么解决这个问题?

编辑:这是我用来安装sklearn的命令:

sudo pip3 install -U scikit-learn

我已经解决了删除sklearn并安装git版本的问题https://askubuntu.com/questions/449326/installation-error-in-sklearn-for-python3
