I am using ns-3.16 in ubuntu 12.04. I'm new to python as well as ns3. When I run this ./waf (or any other waf command) it produces the following code:
Waf: Entering directory `/home/hp/ns-3.16-git-master/build'
Waf: Leaving directory `/home/hp/ns-3.16-git-master/build'
Traceback (most recent call last):

How should I troubleshoot this?
