dataset

    'frames_dir': '/home/ubuntu/Furqan/new_dataset/20231004-activity-all-annotated-tasks/',
    'frame_list': '/home/ubuntu/hammad/YOWOv2/config/frame/',
    'annotation_dir': '/home/ubuntu/hammad/new_annotations/',
    'train_gt_box_list': '/home/ubuntu/hammad/new_annotations/20231005_ke_activity_train_avastyle_17.csv',
    'val_gt_box_list': '/home/ubuntu/hammad/new_annotations/20231005_ke_activity_val_avastyle_17.csv',
    'train_exclusion_file': '/home/ubuntu/hammad/new_annotations/ava_train_excluded_timestamps_v2.2 (1).csv',
    'val_exclusion_file': '/home/ubuntu/hammad/new_annotations/ava_val_excluded_timestamps_v2.2.csv',
    'labelmap_file': '/home/ubuntu/hammad/YOWOv2/labels.pbtxt',  # 'ava_v2.2/ava_action_list_v2.2.pbtxt',
    'class_ratio_file': None,
    'backup_dir': 'results/',

    **however it give me this error**

你好，请问，请问为什么进行DDP训练损失异常的大，但是进行单卡训练没有这种情况。谢谢解答

你好，请问，请问为什么进行DDP训练损失异常的大，但是进行单卡训练没有这种情况。谢谢解答你好，请问你的DDP训练的时候，是不是多张卡都有用到，我这里使用的服务器是四张显卡的，但是使用官方提供的ddp命令训练只使用到了一张卡，你有出现这种情况吗
