Hello, I am new to graph-tool. So, I installed it on Mac OS X using the command sudo port install py-graph-tool. Installation was complete and I went on to run my python code. This is what I got: Traceback (most recent call last): File "SIR.py", line 1, in <module> from graph_tool.all import * ImportError: No module named graph_tool.all The piece of code that created this so called error: from graph_tool.all import * from random import * import smallworld I figured that after installing py-graph-tool, it should work. What I already tried is adding this line to .profile: export PYTHONPATH=/usr/local/lib/python2.7/site-packages/ However, no success. Please, help me out here.
