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

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。
不要乱改 sys.path。一般建议直接安装系统软件源里的包。如果嫌旧了，自己安装也安装到标准路径，这样不需要自己折腾。
看你的情况，你应该把 '/home/users/kuangzhexi/.jumbo/lib/python2.7/site-packages' 加入到 sys.path。下边有个 numpy 目录，就是你的 numpy 包了。
