Problem

fix: DALI warmup slicing can leave empty list before min()

Fix

Replace:

        all_speeds = sorted(all_speeds)[systems:]
        image_type_match[num] = _update_results(image_type_match[num],
                                                all_speeds)

with:

        all_speeds = sorted(all_speeds)
        if len(all_speeds) <= systems:
            print(f'Warning: Not enough DALI speed samples in {log_file}; '
                  'skipping...')
            return {}
        all_speeds = all_speeds[systems:]
        image_type_match[num] = _update_results(image_type_match[num],
                                                all_speeds)
