[tune] Search algorithm supporting discrete hyperparameters, resuming and setting initial points

I’ve tried lots of search algorithms, but failed to find one that supports discrete hyperparameters, resuming from previous tune run and setting initial points at the same time.

Is there one search algorithm that meets all my need?

Thanks in advance.

Does hyperopt work for you? I think it should support all of the above?

@rliaw Unfortunately not.

HyperOpt don’t support setting initial points, as mentioned in this issue.
