MultiCoreBPRMF different results #473

Open jordansilva opened 7 years ago

jordansilva commented 7 years ago

The MultiCoreBPRMF return different results training with the same parameters and fixing the Random Seed. Still, BPRMF (without MultiCore) gets the same results when the Random Seed is fixed.

That looks like a race condition. Not sure whether we will fix this. Should we document the behavior?
