ipython notebook 导入numpy异常如何解决，ipythonnumpy,我在server上安装了

我在server上安装了ipython notebook。启动后import numpy报如下异常：

---------------------------------------------------------------------------ImportError                               Traceback (most recent call last)<ipython-input-3-5a0bd626bb1d> in <module>()----> 1 import numpy/home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages/numpy/__init__.py in <module>()151         return loader(*packages, **options)152 --> 153     from . import add_newdocs154     __all__ = ['add_newdocs', 'ModuleDeprecationWarning']155 /home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages/numpy/add_newdocs.py in <module>() 11 from __future__ import division, absolute_import, print_function 12 ---> 13 from numpy.lib import add_newdoc 14  15 ###############################################################################/home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages/numpy/lib/__init__.py in <module>() 15 from .ufunclike import * 16 ---> 17 from . import scimath as emath 18 from .polynomial import * 19 #import convertcodeImportError: cannot import name scimath

我看了stackoverflow如下两个答案：
http://stackoverflow.com/questions/26238004/ipython-notebook-throws-importerror-ipython-doesnt
http://stackoverflow.com/questions/15514593/importerror-no-module-named-when-trying-to-run-python-script/15622021#15622021
我的操作是：
sys.path.append('/home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages/numpy/lib')
sys.path.append('/home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages/numpy/')
但是还是不行。
