run error and questions about data format #7

Open BraveY opened 6 years ago

BraveY commented 6 years ago

Hi, i'm studying the brilliant system. After deploying the system ,i got error 'Segmentation fault (core dumped)' when i tried to run it . Is there any suggestion for this error ? More else, where can i got the file 'twitter-2010.binedgelist'? If it is possibile , Would you please offer some test files in this project so that users could run this system more conveniently without worrying the data format. Thanks

Hi. Can your provide more detailed information? You may use gdb to locate the detailed position where the segmentation fault happens. For the twitter-2010 data, you can first go to the WebGraph Dataset page and then write a program to extract the edges and write them to an output file in binary format.

@coolerzxw So do you mean that based on current project, the only way of reading the graph is read from a binary format from a regulated exact format? If is, I think the data reading part could be more flexible. If you need the part I think I am willing to help. (I am currently trying this on a practical problem before this I used GraphX) qiu hui fu 3q! ╮(╯▽╰)╭

@SummerLitchy Yes the current implementation can only read from binary edge list files. It would be great if you can enhance the input/output implementation!
