resolve_seed

bayesflow.utils.resolve_seed(seed, seed_generator)

Resolve a user-provided seed against an instance’s own seed generator.

An integer is converted to a fresh SeedGenerator, a SeedGenerator is passed through unchanged, and None falls back to seed_generator.

Every object that owns randomness passes its own self.seed_generator here, whether it draws itself or fans the seed out to sub-components. Draws therefore never fall through to Keras’ global generator (which cannot be traced under jax.jit), and an integer seed becomes one generator shared by all sub-components and batches of the call, rather than one identically seeded generator per draw site.
