How to seed the PRNG such that ffcv results are reproducible? #164

What random seeds do I need to set in order to ensure that I get deterministic results out of ffcv?

You need to limit your self to a single worker otherwise the scheduling randomness will vary the results. You also need to set a seed in the worker. Everything else should be considered a bug I think
