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 "<stdin>",line 1,in <module> File "/usr/local/lib/python2.7/dist-packages/numpy/__init__.py",line 153,in <module> from . import add_newdocs File "/usr/local/lib/python2.7/dist-packages/numpy/add_newdocs.py",line 13,in <module> from numpy.lib import add_newdoc File "/usr/local/lib/python2.7/dist-packages/numpy/lib/__init__.py",line 18,in <module> from .polynomial import * File "/usr/local/lib/python2.7/dist-packages/numpy/lib/polynomial.py",line 19,in <module> from numpy.linalg import eigvals,lstsq,inv File "/usr/local/lib/python2.7/dist-packages/numpy/linalg/__init__.py",line 50,in <module> from .linalg import * File "/usr/local/lib/python2.7/dist-packages/numpy/linalg/linalg.py",line 29,in <module> 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：
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
