Seeding #11

Closed ebergstr closed 5 years ago

ebergstr commented 5 years ago

Is there a way to set our own seed for reproducibility purposes? Similarly for ensuring different streams while parallelizing code...

lemire commented 5 years ago

Have you tried, for example, pcg32_seed?

ebergstr commented 5 years ago

That does not appear to be an available module:

AttributeError: module 'fastrand' has no attribute 'pcg32_seed'

EDIT: I realized the package has been updated since I downloaded it. The module is now present, however, i get a "Segmentation fault" when attempting to pass my own seed.

Yes. This should be fixed in version 1.2. Can you check? If not available now, it should soon be available.

It appears to be working now, thanks!
