Matthias Boehm commented on SYSTEMML-2403:
------------------------------------------
I just ran this scenario several times with different numbers of workers but
was not able to reproduce this (I always get {{Val Accuracy: 0.8915}}). Maybe a
previous change fixes some side effect? Let's keep this task open for now - if
we don't encounter this issue again in the next weeks, we can close it.
