我们的实现方法加入了单独的image token标记图片位置，这在原模型中是没有的。您需要在模型的config.py文件中添加"image_token_index":92544

我们统一用<image>作为image token，请检查下输入文本中image token的总数量与输入图片的总数量是否一致

我们统一用<image>作为image token，请检查下输入文本中image token的总数量与输入图片的总数量是否一致这个是没问题的。
我猜测是padding的问题，internXC2的pad_token_id是2，对应embedding为零向量，在执行final_embedding[image_to_overwrite] = image_features.contiguous().reshape(-1, embed_dim).to(target_device)的时候报错

方便展示一下internXC2模型的config.py文件吗

可以参考我们放出的checkpoint: https://huggingface.co/TideDra/internlm-xcomposer2-vl-7b-DPO/blob/main/config.json

internXC2 的DPO代码还是跑不起来，您确定repo里是最新版本的代码吗？是不是repo是之前的版本导致有些bug没有修复
