title: ImportError: liblapack.so.3gf: cannot open shared object file: No such file or directory
body: <p>I have both python 2.7.16 and python 3.5.2 installed on my ubuntu 16.04 LTS and numpy used to work well on both of them but recently something went wrong with numpy on python 2 while it still running smoothly on python 3</p>
  
  <p>I have tried to uninstall and install the numpy package and this did not fix anything</p>
  
  <p>The exact stdout I am getting is as follow:</p>
  
  <pre><code>python -c "import numpy as np"
