Since release v0.6.0 of pymoo yesterday (https://github.com/anyoptimization/pymoo/releases/tag/0.6.0), HEBO's acq_optimizers fail to import because of an ImportError during the module's own imports:

  tests/unittests/algo/long/hebo/test_hebo.py:9: in <module>
      from hebo.models.model_factory import model_dict
  .tox/algo/lib/python3.7/site-packages/hebo/__init__.py:10: in <module>
      from . import acq_optimizers
  .tox/algo/lib/python3.7/site-packages/hebo/acq_optimizers/__init__.py:10: in <module>
      from . import evolution_optimizer
  .tox/algo/lib/python3.7/site-packages/hebo/acq_optimizers/evolution_optimizer.py:15: in <module>
      from pymoo.operators.mixed_variable_operator import MixedVariableMutation, MixedVariableCrossover

Indeed, pymoo==0.6.0 causes import issues

same here, also pymoo 0.5.0 only support up to python 3.8, so for python 3.9 and 3.10, there's no way to use hebo

I may have a fix here: #35

Latest numpy release does not contain numpy.object anymore, which is now causing even pymoo==0.5.0 to fail.

This should be fixed with the upgrade to v0.3.5.
