Issue with Modularity about gephi-toolkit HOT 19 CLOSED

I modified the Gephi code for Modularity.java and stopped it from being asynchronous. I did this by removing

implements Statistics, LongTask

and all associated code from these packages:

import org.gephi.statistics.spi.Statistics;
import org.gephi.utils.longtask.spi.LongTask;
import org.gephi.utils.progress.Progress;
import org.gephi.utils.progress.ProgressTicket;

The class now works. I hope this helps you identify the bug.

I use a java program to build my .gexf and use this file for both the toolkit and the app. I'll run some more tests tomorrow, and ensure there are no parallel edges. Thanks for the help!

Thanks! I will check it later

Hi, this is already reported at gephi/gephi#1630 and is in the list of priority fixes.

from gephi-toolkit.

Oh I see. It works perfectly in the desktop application, just not in the toolkit.

Do you have any suggestions on how I could maybe get it to work? If I can automate the modularity it would speed my work up a lot :)

from gephi-toolkit.

We still need to find the bug, though it should not work for you in desktop app either. You can try to avoid parallel edges, since maybe this is other bug already fixed in desktop but not released in toolkit.

from gephi-toolkit.

I've opened my .gexf in the Gephi app (0.9.1) and I can see that it is merging the parallel weights. I then save this file from Gephi app to a new .gexf.

When I use this new .gexf, the hanging issue still occurs and finish() is never called.

I can't identify why the Gephi app works, and the toolkit does not.

I hope this helps - good luck with the bug :)

That's strange, can you show your java code? Or compare with this example https://github.com/gephi/gephi-toolkit-demos/blob/master/src/main/java/org/gephi/toolkit/demos/HeadlessSimple.java

from gephi-toolkit.

Sure: https://gist.github.com/Jonty800/d284ff55fb55cd42bb49622b90052ba9

The ProgressTicket just prints out some lines so that I can identify which method is being called.

from gephi-toolkit.

Mmm can you try to pass the graphModel instead of graph like in https://github.com/gephi/gephi-toolkit-demos/blob/master/src/main/java/org/gephi/toolkit/demos/PartitionGraph.java ?

from gephi-toolkit.

Yup, I tried with both graph and graphModel since you can use either. The same happens with both.

from gephi-toolkit.

I see, you can also try to use the latest 0.9.2 snapshot build:

https://github.com/gephi/gephi-toolkit#nightly-builds-092-snapshot

from gephi-toolkit.

I tried this a couple of days ago with gephi-toolkit-0.9.2-20170504.212034-186-all - same thing

from gephi-toolkit.

Ok, will you mail me your test file for reproducing it please? Or attach a zip here if you can

from gephi-toolkit.

gephi files.zip

Sure -> here is the .gexf produced by my java code, and the same file but opened and then saved by gephi

from gephi-toolkit.

This seems to work with latest toolkit 0.9.2-SNAPSHOT. Can you also test it please?

from gephi-toolkit.

Sorry for the late reply, it's been a while since I've needed to use Gephi.

I've been testing the 0.9.3-SNAPSHOT of the toolkit and I seem to get the same problem (only start() method is called, and then it hangs).

My gexf is created using java code only. There are duplicates (A vs B, B vs A), as you can see, for edges:

Any thoughts?

from gephi-toolkit.

I have experienced the same issue too with multiple threads involved. I thought it was related to the mess of projects/workspaces, but I will give the above tricks @Jonty800 has provided a try and provide updates soon. Finger crossed :)

from gephi-toolkit.

Closing old issue. I can't reproduce it. Feel free to reopen with additional details. I've added a label on gephi/gephi#1630 to check whether this is still happening.
