Tsfresh determinism

[btvd]

Hey, tsfresh team!
Can you explain how to lock tsfresh calculations to make it deterministic? I've tried to extract features on different compute sources with the same code with fized random_seed, and see that there are pull of features connected with fourier transformation that give completly different outputs (not even close at precision e-15). Thank you for help!

Hi @btvd !
Sorry for the late response. Fourier transformation itself should definitely not be non-deterministic! So this does sound more like a bug.
Do you know which feature calculators explicitly are problematic? And is it possible to share the data you have been using for your experiments? Or maybe a smaller reproducer?
Thanks for taking the time!
