A small module to hold a class for a temporary seed, so as to not mess with any global seed.

class argosim.rand_utils.local_seed(seed=None)

Bases: object

Holds a seed for use with numpy.random in a local scope.

Can be instantiated with no seed, in which case it will yield the default behaviour. Note that if seed is set to the same seed numpy was using outside this scope, that doesn’t mean the state is the same – if you intend to keep the same state, use seed = None.

seed

The seed used for numpy.random in the local scope.

Type:

int, optional

old_state

The state of numpy.random outside this scope, to be resumed afterwards.
