Describe the bug
我在使用FastConvMAE在imagenet-1k数据集上做预训练的时候，报错为下图

我查看了报错的图片是存在的，不知道为什么路径报错后面会加上label，而且data_train_root无论怎么改报错的地址都不变就算为空也一样，而且就算我改变目录结构直接把图片放到imagenet文件夹而不是imagenet\train文件夹下时也报一样的错
To Reproduce

• What command or script did you run?
  python -m torch.distributed.launch --nproc_per_node=3 --master_port=29930
  tools/train.py
  configs/selfsup/fast_convmae/fast_convmae_vit_base_patch16_8xb64_50e.py
  --work_dir ./work_dir
  --launcher pytorch
• Did you make any modifications on the code or config? Did you understand what you have modified?
• 我将EasyCV/configs/selfsup/fast_convmae/fast_convmae_vit_base_patch16_8xb64_50e.py中的修改如下：
• data_train_list = 'data/imagenet/meta/train.txt'
• data_train_root = 'data/imagenet/train'
• What dataset did you use?
  imagenet-1k格式如下
  EasyCV/data/imagenet

mae的数据格式不需要lable，把每行的label去掉
