Submit child runs from a pipeline step

I would like to submit child runs from within a pipeline step. Specifically, the script in my `PythonScriptStep` has a for-loop to train a model with different parameters. I would like each step in the for-loop to be submitted to a node in my compute cluster. How can I do that? I am thinking I could use [`Run.submit_child()`](https://docs.microsoft.com/en-us/python/api/azureml-core/azureml.core.run(class)?view=azure-ml-py#azureml-core-run-submit-child) inside the for loop to spawn multiple jobs. Is there any guide on how to do so?
