basically:
` from trains import Task

task = Task.init("test", "test", "controller")
task.upload_artifact("test-artifact", dict(foo="bar"))
cloned_task = Task.clone(task, name="test", parent=task.task_id)
cloned_task.data.script.entry_point = "test_task_b.py"
cloned_task._update_script(cloned_task.data.script)
cloned_task.set_parameters(**{"artifact_name": "test-artifact"})
Task.enqueue(cloned_task, queue_name="default") `
