Hi, I am trying to do some hyperparameter search with ClearML. I would like to define a logarithmic uniform range for some hyperparams but the options I find are UniformParameterRange and UniformIntegerParameterRange which I assume are linear ranges. Is there any other option to define ranges?

I was looking at optuna package and noticed that they raise this ValueError:
if step is not None: if log: raise ValueError("The parameterstepis not supported whenlogis True.")So step_size should always be None

Looks great, nice solution and easy to implement, thanks!

Hey LethalDolphin75 , when it works, could you PR it?

And the low and high values are already the log value. For example it couldbe sth like low=1e-6, high=1e-3 ; and not low=-6, high=-3 .

I'm having another problem now because I am using the OptunaOptimizer.

Hmm let me check a sec

LethalDolphin75 Yes you are correct, we should add here:
https://github.com/allegroai/clearml/blob/400c6ec103d9f2193694c54d7491bb1a74bbe8e8/clearml/automation/optuna/optuna.py#L210
elif isinstance(p, UniformLogarithmicParameterRange): hp_type = 'suggest_float' hp_params = dict(low=p.min_value, high=p.max_value if p.include_max else p.max_value - p.step_size, log=True, step=p.step_size)btw: I'm not sure if the min/max values should be before or after log (i.e. low=log(p.min_value) or low=p.min_value )
