JitteryCoyote63 correct, you could also use Task.create that creates a Task but does not do any automagic.
I also saw the PR for set_parent, will be merged shortly 🙂 thanks!
Now I see, the scenario is similar to the HyperParameter scenario , see the TrainsJob https://github.com/allegroai/trains/blob/master/trains/automation/job.py
I still don't see why you would change the type of the cloned Task, I'm assuming the original Task had the correct type, no?
