2012-01-21 09:11:35 +0100 | marked best answer | can't use networkx.read_dot() Have you installed the optional package http://www.sagemath.org/packages/opti... If not this command won't work. Run the command sage -i dot2tex-2.8.7-2 to install it. You can find a list of optional packages at http://www.sagemath.org/packages/opti... Edit: Sorry I posted that without trying it out just by looking at the manual, but I managed to solve the problem. Here are the steps I did to make it run. 1) install optional package dot2tex 2) install optional package graphviz from the same page (http://www.sagemath.org/packages/opti...) 3) At the terminal type $sage -sh $easy_install pygraphviz That way I was able to run a simple pygraphviz example. |
