Question

我想导入sage和sklearn模块，但当我尝试导入它们时，两个sage show ImportError：

$ sage -python temp.py 
Traceback (most recent call last):
  File "temp.py", line 2, in <module>
    from sklearn import *
ImportError: No module named sklearn

已安装所有sklean模块：

$ ipython2
In [1]: from sklearn import *
/usr/lib/python2.7/site-packages/sklearn/pls.py:7: DeprecationWarning: 
This module has been moved to cross_decomposition and will be removed in 0.16
"removed in 0.16", DeprecationWarning)

$ ipython3
In [1]: from sklearn import *
/usr/lib/python3.4/site-packages/sklearn/pls.py:7: DeprecationWarning:
This module has been moved to cross_decomposition and will be removed in 0.16
"removed in 0.16", DeprecationWarning)

我会打赌你的 Sage 版本的Python中没有安装它的大量迷你甜甜圈。

$ sage -ipython
Python 2.7.5 (default, May  6 2014, 09:27:46) 
Type "copyright", "credits" or "license" for more information.

IPython 1.2.1 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: from sklearn import *
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: No module named sklearn

假设你已经有pip，我会做

$ sage -sh

Starting subshell with Sage environment variables set.  Don't forget
to exit when you are done.  Beware:
 * Do not do anything with other copies of Sage on your system.
 * Do not use this for installing Sage packages using "sage -i" or for
   running "make" at Sage's root directory.  These should be done
   outside the Sage shell.

Bypassing shell configuration files...

Note: SAGE_ROOT=...
(sage-sh) :~$

然后您可以在那里安装sklearn。您需要执行Sage shell命令，否则它将无法选择正确的环境变量来正确安装它。但是，一旦你完成了这个，你应该很高兴。

用鼠尾草在python中导入skitlean模块
