SweetBadger76 CostlyOstrich36 after trying to run the same code (and ignoring the warning) i get a different error:
ValueError: HyperParameter type <class ‘clearml.automation.parameters.ParameterSet’> not supported yet with OptimizerBOHB
I looked at the “OptimizerOptuna” code, (clearml/automation/optuna/optuna.py) and i saw that the paramset is really not suppurted.
Which optimizer support parameterset?

Thanks! I added an issue

Last (very) little thing : could you please open a Github issue for this irrelevant warning 🙏 ? It makes sense to register on GH those bugs, because our code and releases are hosted there.
Thank you !

Just to keep you updated, as promised 🙂
we have found the bug and will release a fix asap. for that too i will keep you updated 🙂

Concerning how to use ParameterSet :
I first declare the set
my_param_set = ParameterSet([ {'General/batch_size': 32, 'General/epochs': 30}, {'General/batch_size': 64, 'General/epochs': 20}, {'General/batch_size': 128, 'General/epochs': 10} ])This is a very basic example, it is also possible to use more complex things into the set (see https://clear.ml/docs/latest/docs/references/sdk/hpo_parameters_parameterset/ for UniformParameter Range usage in ParameterSet).

Then i do as you did 🙂
`

optimizer = HyperParameterOptimizer(
# specifying the task to be optimized, task must be in system already so it can be cloned
base_task_id=args['template_task_id'],
# setting the hyper-parameters to optimize
hyper_parameters=[
my_param_set,
], `
If you need something more complete/complex, do not hesitate to ask 🙂 I kept simple here because you already do it fine

ps. concerning the warning, i am going to enquire, and will keep you updated

hi MoodySheep3
I think that you use ParameterSet the way it is supposed to be 🙂
When I run my examples, I also get this warning - which is weird ! because
This is just a warning, the script continues anyway (and reaches end without issue) Those HP exists - and all the sub tasks corresponding to a given parameters set find them !

Can you maybe provide me an example of how to use the parameterset?

MoodySheep3 , a screenshot would be useful just to understand the structure via UI 🙂

Is it enough ? CostlyOstrich36

Can you please add a screenshot of how the hyper params show in the UI for you?

Also how are you running the HPO? From the examples?

Hi MoodySheep3 ,

Can you please provide screenshots from the experiment - how the configuration looks like
