Enable `objective(study.best_trial)`
See original GitHub issueI find it useful to be able to re-run trials to investigate them further, e.g. with more debugging/data reporting enabled. I thought that it would be natural if I could manually run a trial from a study e.g. by:
my_objective(my_study.best_trial, more_reporting=True)
but given that the objective function calls various suggest_* methods, I get AttributeError: 'FrozenTrial' object has no attribute 'suggest_int'. And instead I need to do:
my_objective(optuna.trial.FixedTrial(my_study.best_trial.params, my_study.best_trial.number), more_reporting=True)
Making my_objective(my_study.best_trial) work would be a small, but useful improvement in my workflow.

@keisuke-umezawa Thank you for your reply! But I’m a little bit busy and not good health condition this July, so I create PR for this issue if this issue’s priority is not so high… Is it okay?
Let me close this issue because this feature has been introduced in #1503.
