  As I know, there is not a good tutorial explainging how to import sage packages in python. When I
  list_packages of sage, it shows that
  numpy, scipy, python_igraph are installed. Then I want to import these packages in python with the following codes
  from sage.all import *
  I can use
  numpy, scipy while
  python_igraph does not work. Could anyone explain why
  numpy, scipy work while
  python_igraph does not? How to get
  python_igraph work?
  And what packages in sage can I use in python? Is there any explicit tutorial?
