有关Internvl-1.5的微调实验（AttributeError: 'NoneType' object has no attribute 'shape'）

[MVP-D77]

@hjh0119 在1.5版本微调训练结束后，按照教程里面的推理命令，并加载了本地的权重，我使用的infer命令如下：

CUDA_VISIBLE_DEVICES=0,1 swift infer  --ckpt_dir output/internvl-chat-v1_5/v0-20240512-191616/checkpoint-25 --load_dataset_config true  --dtype bf16  --model_id_or_path xxxxx/InternVL/pretrained/InternVL-Chat-V1-5

但在加载后出现了报错情况，不知之前测试时有没有发生
