Doesn't work with bayes-optim 0.2.6

[Stepets]

Steps to reproduce

install latest nevergrad, bayes-optim

  pip3 install nevergrad
  pip3 install bayes-optim

Observed Results

Traceback (most recent call last):
  File "/home/user/projects/advbiz-docker/scripts/optimiser/nevergrad/run_all.py", line 43, in <module>

TypeError: GaussianProcess.__init__() got an unexpected keyword argument 'thetaL'

Expected Results

No error

Relevant Code

  instrum = ng.p.Instrumentation(ng.p.Array(shape=(2,), lower=-50, upper=50))
  ng.optimizers.registry["BayesOptimBO"](parametrization=instrum, budget=100, num_workers=1)

Bayes-optim has changed API https://github.com/wangronin/Bayesian-Optimization/blob/94af6af6f12cc013a884a8e309e1e089c3cd7481/bayes_optim/surrogate/gaussian_process/__init__.py#L31 So I had to downgrade to 0.2.5.5 version for optimization to work

This is fixed in Nevergrad 0.12.0, we can work with the latest, namely 0.3.0. Thanks for pointing out this.
