[Clarkszw]

Hi Aiida experts.
I am running the exerises in this page with
pseudo_family = load_group('PseudoDojo/0.4/PBE/SR/standard/upf')
But the process state keep as "Created"..
I have tried
verdi daemon start
and
verdi daemon restart
neither helped to start the process..
Could you help me with this?
Thanks in advance.
