ubuntu - libatlas.so.3gf: cannot open shared object file -

i not able make sklearn function on ubuntu 12.04 box. error getting. not sure how around it?

from sklearn.manifold import tsne  # gives below error importerror: libatlas.so.3gf: cannot open shared object file: no such file or directory 

here output of ls /usr/lib/atlas-base/

atlas not seem recommended library. openblas recommended library. if numpy configured work easily.

link existing numpy libraries: link atlas/mkl installed numpy compile numpy openblas: compiling numpy openblas integration

so, in such problem uninstall existing numpy , try above 2 links. work fine. installation using 2nd link best option. once , never worry it.
