Attempting to train this on a real workload I converted over the weekend after, "step" 8M~ so far and rarely scores above 5% and most are 0% but has scored 60% once 7M~ steps ago.

Adding more than 1 GPU didn't improve speed but that's pretty standard as we don't have fancy interconnect. Bit annoying they didn't use tensorboard for logging, but overall seems like a pretty cool lib - will leave it a few days and see if it can learn (no other algo has so I dont have much hope).
