title: Unable to locate the installed graph-tool package in Python
body: <p>I spent 1 hr 30mins to install graph-tool package. Installation declared that it was successful. When I tried to import it says "no module by name graph_tool..." I guess I am missing the path or link to this module. How to link or import?  </p>
  
  <p>Also, when I ran the command "pip freeze" it does not show the graph_tool package installed. Please help to resolve these problems. Thanks. </p>
