e.g.my_optimizer = an_optimizer.get_optimizer() plot_optimization_history(my_optimizer._study)
Since my_optimizer._study
is an optuna object
Hi EmbarrassedSpider34 , what is your use-case? Isn't the Optimizer object something like a Task object? Since it's a process I'm not sure you can pickle it. wdyt?
So anyway,
you can pickle the above object (pickle the study).
But you can't actually pickle the optimizer itself as you said/
