correct, you could also use

Task.create

that creates a Task but does not do any automagic.

Yes, I didn't use it so far because I didn't know what to expect since the doc states:
"Create a new, non-reproducible Task (experiment). This is called a sub-task."

Thanks for the hack! The use case is the following: I have a controler that creates training/validation/testing tasks by cloning (so that the parent task id is properly set to the controler). Otherwise I could simply create these tasks with Task.init, but then I would need to set manually the parent task for each one of these tasks, probably with a similar hack, right?

Hi JitteryCoyote63 , I have to admit, we have not thought of this scenario... what's the exact use case to clone a Task and change the type?

Obviously you can always change the task type, a bit of a hack but should work:
task._edit(type='testing')

Sorry that was a reply to:

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?

Because it is easier for me that I create a training task out of the controller task by cloning it (so that parameters are prefilled and I can set the parent task id)

Ohh I see, makes total sense. I'm assuming the code base itself can do both 🙂
