DeepGL algo doesnt seem to finish #5

Open tomasonjo opened 5 years ago

tomasonjo commented 5 years ago

Load data:

:play movies

Run algorithm:

CALL embedding.deepgl(null ,null)

Inspecting the logs it seems that algorithm get quickly to: 

2018-10-06 08:03:38.268+0000 INFO  [neo4j.BoltWorker-3 [bolt] [/127.0.0.1:54242] ] DeepGL 100% Size of combined embedding: [171, 28379]

but the next step doesn't finish more than 10 minutes after.

How many iterations has it run at that stage? It should say just above what you pasted in the logs.

I think our default number of iterations may be too high.

Ok looking at iterations...

It takes 45s to get to the fifth iteration

Then it really slows down with taking just under 4 minutes to finish fifth iteration and 13 minutes to finish sixth iteration
