method
random.RandomState.set_state(state)
Set the internal state of the generator from a tuple.
For use if one has reason to manually (re-)set the internal state of the bit generator used by the RandomState instance. By default, RandomState uses the “Mersenne Twister”
pseudo-random number generating algorithm.
Parameters:state{tuple(str, ndarray of 624 uints, int, int, float), dict}The state tuple has the following items:
the string ‘MT19937’, specifying the Mersenne Twister algorithm.
a 1-D array of 624 unsigned integers keys.
an integer pos.
an integer has_gauss.
a float cached_gaussian.
If state is a dictionary, it is directly set using the BitGenerators state property.
Returns:outNoneReturns ‘None’ on success.
Notes
and
are not needed to work with any of the random distributions in NumPy. If the internal state is manually altered, the user should know exactly what he/she is doing.
For backwards compatibility, the form (str, array of 624 uints, int) is also accepted although it is missing some information about the cached Gaussian value: state=('MT19937',keys,pos).
