[MRG+1] Fix Docstring for random_state in RandomizedSearchCV inaccurate
@@ -1127,6 +1127,12 @@ class RandomizedSearchCV(BaseSearchCV):
It is highly recommended to use continuous distributions for continuous
parameters.
+ Note that before SciPy 0.16, the ``scipy.stats.distributions`` do not
+ accept a custom RNG instance and always use the singleton RNG from
+ ``numpy.random``. Hence setting ``random_state`` will not guarantee a
+ deterministic iteration whenever ``scipy.stats`` distributions are used to
+ define the parameter search space.
