最近开发同事让我装几个包，scipy、gensim、theano、sklearn.....几个包装完后，发现导入报错，具体如下:
from ._ufuncs import (ellipkm1, mathieu_a, mathieu_b, iv, jv, gamma,
ImportError: cannot import name ‘_zeta‘
通过某度搜了好久愣是没发现解决办法，后来直接出去，用Google搜索，直接提示scipy版本问题，更新即可，
Sounds like you have an old version of special._ufuncs--the function zeta in there was renamed to_zeta somewhat recently. What happens if you completely uninstall SciPy and then reinstall a fresh version? (Also, what version of SciPy are you using?)
这里真的不得不吐槽一把....
[root@localhost~]# pip uninstall scipy
[root@localhost~]# pip install -U scipy
后面的安装过程大概需要10分钟左右，最终结果为:
Could not find .egg-info directory in install record for scipy from https://pypi.python.org/packages/22/41/b1538a75309ae4913cdbbdc8d1cc54cae6d37981d2759532c1aa37a41121/scipy-0.18.1.tar.gz#md5=5fb5fb7ccb113ab3a039702b6c2f3327 in /usr/local/lib/python2.7/site-packages
Successfully installed scipy
Cleaning up...
