UserWarning：已经导入了模块fipy

Question

当我尝试从python提示符导入fipy时出现以下错误。

>>>import fipy    
/home/jana/Builds/lib/python2.6/site-packages/fipy/__init__.py:34: UserWarning: Module     fipy was already imported from /home/jana/Builds/lib/python2.6/site-packages/fipy/__init__.py, but /home/jana/Builds/lib/python2.6/site-packages is being added to sys.path 
from pkg_resources import get_distribution, DistributionNotFound 

我在安装fipy时使用了stowy。我在这里查看了类似的错误，但他们提到了两个不同目录的导入。我在错误消息中重复了相同的路径。
