Hi All, I am new to Graph-tool and learning the basic operation on the Graph. The below command confused me a lot.
--------------------------------------------- Python 3.5.2 (default, Nov 17 2016, 17:05:23) [GCC 5.4.0 20160609] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from graph_tool.all import * >>> >>> >>> Failed to connect to Mir: Failed to connect to server socket: No such file or directory Unable to init server: Could not connect: Connection refused Failed to connect to Mir: Failed to connect to server socket: No such file or directory Unable to init server: Could not connect: Connection refused >>> G=Graph(directed=False) >>> >>> >>> >>> G.add_vertex() >>> >>> >>> <Vertex object with index '0' at 0x7f70714a00f0> >>> G.add_vertex() <Vertex object with index '1' at 0x7f70714a0210> >>> G.add_vertex() <Vertex object with index '2' at 0x7f70714a00f0> >>> G.add_vertex() <Vertex object with index '3' at 0x7f70714a0210> >>> G.add_vertex() <Vertex object with index '4' at 0x7f70714a00f0> >>> G.add_vertex() <Vertex object with index '5' at 0x7f70714a0210> >>> G.add_vertex() <Vertex object with index '6' at 0x7f70714a00f0> >>> G.add_edge(1,2) >>> >>> >>> <Edge object with source '1' and target '2' at 0x7f7085fca9d0> >>> print(G) <Graph object, undirected, with 7 vertices and 1 edge at 0x7f70967c5400> >>> G.clear_vertex(1) >>> >>> >>> >>> print(G) >>> >>> >>> <Graph object, undirected, with 7 vertices and 1 edge at 0x7f70967c5400> >>> G.clear_vertex(2) >>> >>> >>> >>> print(G) >>> >>> >>> <Graph object, undirected, with 7 vertices and 1 edge at 0x7f70967c5400> --------------------------------------------- I know the clear_vertex is to clear all edges related with the Vertex. But after executing the clear_vertex, it seems that the Graph still contains 1 edge created before. Will I need to revise my code ? I post the same on the stackoverflow https://stackoverflow.com/questions/45031315/the-basic-usage-in-the-graph-tool-how-to-delete-vertex-and-related-edges-in-the?noredirect=1#comment77045641_45031315 Thank you, Best Regards. -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/The-basic-usage-in-the-Graph-tool-how-to-delete-vertex-and-related-edges-in-the-Graph-tool-tp4027299.html Sent from the Main discussion list for the graph-tool project mailing list archive at Nabble.com. _______________________________________________ graph-tool mailing list [email protected] https://lists.skewed.de/mailman/listinfo/graph-tool
