 numpy出错 解决方案

Problem: how to import numpy in subdirectory? import error of numpy within subfolder.

错误信息：

>>> import numpy 
Traceback (most recent call last): 
 File "", line 1, in  
 File "/usr/local/lib/python2.7/dist-packages/numpy/__init__.py", line 153, in  
  from . import add_newdocs 
 File "/usr/local/lib/python2.7/dist-packages/numpy/add_newdocs.py", line 13, in  
  from numpy.lib import add_newdoc

  from numpy.linalg import lapack_lite, _umath_linalg 
importError: libatlas.so.3gf: cannot open shared object file: No such file or directory 

可能原因：

1. 子文件夹下有自己建的numpy.py文件

2. 看最后一行的错误，找不到libatlas.so.3gf. 将其所在文件夹引入/etc/ld.so.conf,缺啥补啥

$ sudo gedit /etc/ld.so.conf

写入/usr/lib/atlas-base

$ sudo ldconfig
