Converter for BayesSearchCV

[fabiogeraci]

Hello devs,

I am working on a converter for BayesSearchCV, but I getting the following error, I am not sure what I am missing, any help is appreciated.

Error

@fabiogeraci the BayesSearchCV is belonging to skopt instead of sklearn, so we don't have plan to support officially.
