Is it possible to upload from ClearML (using Logger/upload_artifact ) a clearml.automation.optimization.HyperParameterOptimizer object? (as pickle for example)
I am getting this error when trying to pickle the optimizer.
I want to do this in order to use the study (Optuna), and outputs of the optimizer later on.
Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: cannot pickle '_thread.lock' object
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/
