Dear AgitatedDove14 and SmugDolphin23 , i think i have noticed another interesting effect of decorators. When pipeline method has a custom wrapper (decorator) and I trigger the pipeline from clearml UI, then parameters that are provided via the UI are not actually passed to the pipeline method. At the same time custom decorators used on pipeline components and simple functions works exactly the same both when I trigger pipeline locally from the code, or via clearml UI. In my setup i trigger pipeline from clearml UI and it is executed on another machine that runs docker container with clearml agent.
