Issue I encountered:
#542 run test_restore.py and got _pickle.UnpicklingError: state is not a dictionary
I observed:
1. numpy version
i. When numpy==1.16*, np.random.RandomState.__getstate__() returns a tuple, not a dict.
_pickle.UnpicklingError occurs
ii. When numpy>1.17.0rc1, it returns a dict;
_pickle.UnpicklingError does not occur
iii. When numpy>1.17.0rc1, flaml uses np_random_generator = np.random.Generator,
_pickle.UnpicklingError does not occur
2. class _BackwardsCompatibleNumpyRng
When I remove func _BackwardsCompatibleNumpyRng.__getattr__() , _pickle.UnpicklingError doesn't occur (regardless of numpy version == 1.16* or 1.17*)
To sum up,
I think making modifications to class _BackwardsCompatibleNumpyRng is not a good choice (_BackwardsCompatibleNumpyRng came from ray）and we still need to learn more about the operation mechanism of pickle.
So I upgraded the numpy version that flaml requires：
setup.py："NumPy>=1.17.0rc1"
