Hello, graph_tool is installed on ubuntu trusty according to the documentation and when the following code is run from an ipython cell, I have: import graph_tool as gt mG = gt.Graph(directed = False) v1 = mG.add_vertex() v2 = mG.add_vertex() mG.add_edge(v1,v2) print gt.__version__ gt.graph_draw(mG) --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-4-a81ac2c86e8f> in <module>() 4 mG.add_edge(v1,v2) 5 print gt.__version__ ----> 6 gt.graph_draw(mG) AttributeError: 'module' object has no attribute 'graph_draw' 2.2.30 (commit 8ff4701a, Tue Mar 25 13:40:40 2014 +0100) I also tried to build graph-tool from source but the compilation failed due to a lack of virtual memory (1.22 Go RAM and 1.85 Go swap) Thank you for your advices.
