from pybbn.generator.bbngenerator import generate_multi_bbn, convert_for_exact_inference
from pybbn.sampling.sampling import LogicSampler


bbn = convert_for_exact_inference(*generate_multi_bbn(20, max_iter=5_000))

print(sampler.nodes)

samples = sampler.get_samples(n_samples=5, seed=37)

print(samples)

Will result in the following.
