guarantee result reproducibility with seed

[Bae-SungHan]

Hi.

Doing inference with command chai fold {input_fasta} {ouptut_dir} --seed {input_seed} doesn't guarantee fixed result for given seed.
Is there any other things to consider for result reproduciblity?

Thx.

Hi @Bae-SungHan

yeah, some operations we use are not deterministic.

You can try using use_deterministic_algorithms
https://pytorch.org/docs/stable/notes/randomness.html#avoiding-nondeterministic-algorithms

But IIRC it will fail and demand recompiling pytorch to include deterministic version for some operations
