我尝试在自己的数据集上进行了微调，但是当我微调后不论是lora还是全量，在尝试输入图片的时候都出现了报错：

RuntimeError: mat1 and mat2 shapes cannot be multiplied (729x1152 and 3456x4096)

根据调用堆栈，可能是我的projector维度异常发生了改变这是我的微调配置文件：

!/bin/bash

MODEL_TYPE=llama3-8b

PRETRAIN_DIR=bunny-$MODEL_TYPE-pretrain OUTPUT_DIR=bunny-lora-$MODEL_TYPE

mkdir -p ./checkpoints-$MODEL_TYPE/$OUTPUT_DIR

Bunny-v1.1-Llama-3-8B-V is trained with S^2-Wrapper enabled.

So, --use_s2 True

非常感谢，添加参数后模型可以正常运行https://github.com/BAAI-DCAI/Bunny/issues/100#issuecomment-2205975845
