I'll have to trust you. It is not possible to tell from the image that there are only four possible paths. > I would like to extract the order of the edges in the four paths I drew. > > The shortest path solution you described corresponds to path 3 in the drawing. > all_shortest_paths gives my path 3 and another completely different path > before crashing with a memoryError. I'm not sure why you get a memory error. I can only guess, since you are not giving me a concrete example of what you are trying to do (i.e. code). If you are not filtering the graph, or if there are more than 4 possible paths, you may run out of memory if you try to store them all. Note that even if there are 4 paths in the filtered graph, there is definitely a huge number of them in the unmodified graph. If you want to consider all paths instead of the shortest paths, you should use the function all_paths(). If you need more detailed assistance, please provide a _minimal_ and _self-contained_ example that shows the problem. Best, Tiago -- Tiago de Paula Peixoto <[email protected]>
