numpy出錯 解決方案

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

錯誤資訊：

>>> 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 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. 子檔案夾下有自己建的numpy.py檔案

2. 看最後一行的錯誤，找不到libatlas.so.3gf. 将其所在檔案夾引入/etc/ld.so.conf,缺啥補啥

$ sudo gedit /etc/ld.so.conf

寫入/usr/lib/atlas-base

$ sudo ldconfig
