LambdaSimulator

class bayesflow.simulators.LambdaSimulator(sample_fn: callable, *, is_batched: bool = False)

Bases: Simulator

Implements a simulator based on a sampling function.

sample(batch_shape: tuple[int, ...], **kwargs) → dict[str, ndarray]

rejection_sample(batch_shape: tuple[int, ...], predicate: Callable[[dict[str, ndarray]], ndarray], *, axis: int = 0, sample_size: int = None, **kwargs) → dict[str, ndarray]
