[A clear and concise description of what you want to happen.]
Unfortunately, the scikit-optimize was closed on February 29, 2024.
https://github.com/scikit-optimize/scikit-optimize
So we need to stop supporting the skopt suggestion service as well.
I think that we can follow similar deprecation steps as the MXNet.
Anything else you would like to add:

May I work for this issue?

We need to follow the deprecation flow step by step.
PeterWrighten commentedon Mar 10, 2024
Got it. Thanks!

That is sad to hear @tenzen-y.
Do we have any alternative to use Bayesian Optimization in Hyperopt or Optuna ?
tenzen-y commentedon Mar 11, 2024
Unfortunately, both
optunaandHyperoptdon't provide Bayesian sampler.tenzen-y commentedon Mar 11, 2024
If we want to provide Bayesian sample, we need to implement it ourselves.
andreyvelich commentedon Mar 12, 2024
Maybe we could check some Open Source BO implementations.
For example: https://github.com/bayesian-optimization/BayesianOptimization
Also, quite recently @contramundum53 added GPSampler support in Optuna: optuna/optuna#5185
Maybe we can re-use it.
cc @c-bata @a9p for your ideas here.
tenzen-y commentedon Mar 12, 2024
Oh, I didn't find that.
tenzen-y commentedon Mar 12, 2024
So, setting optuna as a default Bayesian sampler might be better.
contramundum53 commentedon Mar 13, 2024
@andreyvelich @tenzen-y I'm glad that you are considering integration of Optuna's
GPSamplerinto katib!GPSampleris planned to be released in Optuna v3.6, our next minor release. It is still experimental and future breaking changes/bugs are possible (the code is only a month old!), but if it's okay for you, we'll be happy to hear that.25 remaining items

If anyone want to work on this issue, we want to migrate to GPSampler from Optuna from skopt to perform bayesian optimization in Katib.
