ImportError:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the multiarray numpy extension module failed.  Most

likely you are trying to import a failed build of numpy.

Here is how to proceed:

- If you're working with a numpy git repository, try `git clean -xdf`

(removes all files not under version control) and rebuild numpy.

- If you are simply trying to use the numpy version that you have installed:

your installation is broken - please reinstall numpy.

- If you have already reinstalled and that did not fix the problem, then:

1. Check that you are using the Python you expect (you're using /usr/bin/python),

and that you have no directories in your PATH or PYTHONPATH that can

interfere with the Python and numpy versions you're trying to use.

2. If (1) looks fine, you can open a new issue at

https://github.com/numpy/numpy/issues.  Please include details on:

- how you installed Python

- how you installed numpy

- your operating system

- whether or not you have multiple versions of Python installed

- if you built from source, your compiler versions and ideally a build log

Note: this error has many possible causes, so please don't comment on

an existing issue about this - open a new one instead.

Original error was: /usr/lib64/python2.6/numpy/core/_multiarray_umath.so: undefined symbol: PyOS_string_to_double

>>>

最终解决：

看起来就是“/usr/lib64/python2.6/”和“/usr/lib64/python2.6/site-packages/”里各有一个numpy。

把“/usr/lib64/python2.6/”里的numpy重命名成了别的，似乎之后就正常了。
