I ran the same script on identical data multiple times, started immediately after another.
the only difference is in the number of workers used, i.e.
gray = 0 workers
pink = 1 worker
blue = 2 workers
green 4 workers
orange is 8 workers
I have put determinism and random seeds on everywhere, except for seeding the workers.
The result in remarkable. Can anyone explain where this vast differences are coming from?
