Fix bug in telemetry.py when trying to load npz file with --arrival or --scale

                if hasattr(args, 'scale') and args.scale:

                    for job in tqdm(jobs, desc=f"Scaling jobs to {args.scale} nodes"):

                        job['nodes_required'] = random.randint(1, args.scale)

                        job['scheduled_nodes'] = None  # Setting to None triggers scheduler to assign nodes

                        job.nodes_required = random.randint(1, args.scale)

                        job.scheduled_nodes = None  # Setting to None triggers scheduler to assign nodes

                if hasattr(args, 'arrival') and args.arrival == 'poisson':

                    print("available nodes:", config['AVAILABLE_NODES'])

                    for job in tqdm(jobs, desc="Rescheduling jobs"):

                        job['scheduled_nodes'] = None

                        job['submit_time'] = next_arrival_byconfargs(config, args)

                        job.scheduled_nodes = None

                        job.submit_time = next_arrival_byconfargs(config, args)

            else:

                trigger_custom_dataloader = True

                break
