UtilityFunction not available anymore

from bayes_opt.util import UtilityFunction

In the shown example, the UtilityFunction is imported but it doesn't seem to be part of bayes_opt anymore.

import bayes_opt

from bayes_opt.util import UtilityFunction

yiels ImportError: cannot import name 'UtilityFunction' from 'bayes_opt.util'

Version:
bayes_opt: 2.0.3

Hi @nilsleh,

thanks for raising the issue. I believe that the file in question should probably be removed from the repository, but I wasn't entirely committed to doing that since I didn't initially add it (see also #503). But you're right in that it has not been maintained correctly and the mismatch is misleading.

May I ask what your usecase is? If there's a good reason to keep it, I can work on making it functional. Otherwise I will probably go through with my original plan and delete it soon.

Hi @till-m , thanks for your reply. The usecase is actually in the linked issue for RayTune where I encountered the bug, and then was searching this repo for UtilityFunction and couldn't find it in the src files anymore. So personally I don't have a use case for the linked file, here, it is just the only one where I found UtilityFunction.
