完整模型过几日上传。

模型 llava-Qwen2-7B-Instruct-Chinese-CLIP 增强中文文字识别能力和表情包内涵识别能力，达到gpt4o、claude-3.5-sonnet的能力！！！！！

1. 模型结构：
   llava-Qwen2-7B-Instruct-Chinese-CLIP = Qwen/Qwen2-7B-Instruct + multi_modal_projector + OFA-Sys/chinese-clip-vit-large-patch14-336px
   

2. 微调模块

• vision_tower和language_model的q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj部分进行lora训练
  
• mmp层全量训练
  

3. 微调
   参数：lora_r=32,lora_alpha=64,num_train_epochs=5,per_device_train_batch_size=1,gradient_accumulation_steps=8,high_lr=1e-3,low_lr=2e-5,model_max_length=2048.
   设备：8*A800
   训练时长：5小时12分钟

4. 数据集
   使用gemini-1.5-pro, gemini-1.5-flash, yi-vision, gpt4o,claude-3.5-sonnet模型描述emo-visual-data和ChineseBQB数据集。
   文本描述信息通过text-description-of-the-meme 下载
   图像可通过emo-visual-data, ChineseBQB下载
   图片数据总量1.8G，约10835张中文表情包图片。文字总量42Mb，约24332个图像文本对描述信息。

5. 效果展示
   以下测试结果显示模型能识别图像中的文字信息，且能正确识别表情包想要表达的内涵。对比REILX/llava-1.5-7b-hf-meme-lora模型中也测试了原始llava-1.5-7b-hf模型的输出，模型无法正确识别图像中的文本信息。
   

   
   以下三张图为gpt4o的识别效果
   

6. 代码
   合并模型代码，合并模型之后将add_tokens.json,merge.txt,preprocessor_config.json,specital_token_map.json,tokenizer.json,vocab.json文件复制到"/保存的完整模型路径"。
