set_seed

set_seed(seed, use_seed_seq=True, net_id=0)

Sets the seed of the random number generators, both in ANNarchy.RandomDistributions and in the C++ library when it is created.

Numpy still has to be seeded explicitly when using the default RNG, for example:

ann.set_seed(seed=42)
rng = np.random.default_rng(seed=42)
A = rng.uniform(0.0, 1.0, (10, 10))

Parameters

Name	Type	Description	Default
seed	int	integer value used to seed the C++ and Numpy RNG	required
use_seed_seq	bool	for openMP and parallel RNGs, we use either the STL SeedSequence (True, default) or a specialized implementation proposed by Melissa O’Neil (False, see _optimization_flags for more details).	True
