to my understating:
failed means that python job exited non gracefully, with errors originated from python

what I miss is how to refer to aborted vs. stopped
does the user initiated the job to stop?
or it's something came from the system running the job?

I did note STATUS MESSAGE: and STATUS REASON:
it N/A in many cases, some get Singal None value, or Forced stop (non-responsive) , but not sure how to refer these fields and what can I learn from them
