[BUG]: numpy.random.mtrand.RandomState object has no attribute integers -> switch to np.random.Generator

[themasterlink]

Hey,

I found a bug, which is easy to fix, the hyperopt backend does not use the deprecated np.random.RandomState anymore and replaced it with np.random.Generator, this means the following line:

bbopt/bbopt/backends/hyperopt.py

Line 176 in 408e210

def setup_backend(self, params, algo=tpe.suggest, rstate=np.random.RandomState(), show_progressbar=False, **options):

Should be changed to:

    def setup_backend(self, params, algo=tpe.suggest, rstate=np.random.default_rng(), show_progressbar=False, **options): 

This is explained in the following issue on hyperopt:

hyperopt/hyperopt#838

Best,
Max

Thanks for the bug report! Should be fixed now in bbopt>=1.3.9.
