| # NewsPicGen | |
| NewsPicGen: News Picture Prompt Generation Model是一个中文新闻配图生成模型,使用[Qwen2.5-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-1.5B-Instruct)作为基座模型,使用SFT进行微调。 | |
| 可以生成与新闻内容相关的高质量的中英双文配图prompt、中英双文关键字和绘画类型。直接通过Stable Diffusion生成配图,可根据绘画类型配置不同的绘图模板,生成多种风格的配图。 | |

| </p> | |
| ## 功能 | |
| - 生成与新闻内容相关的高质量的中英双文配图prompt、中英文关键字和绘画类型。 | |
| - 微调数据使用万级新闻数据,并采用多任务进行SFT微调,在生成绘画prompt的同时,对绘画类型(1.动物、2.人、3.人群、4.风景、5.建筑、6.科技产品、7.物品、8.其他)进行判断,强化模型输出效果。可以针对不同的绘画类型,配置不同的绘画模板。 | |
| - 支持JSON格式化输出,方便后续使用。 | |
| - 生成图片为漫画风格,对于新闻配图有较好的表现。 | |
| ## 性能 | |
| - 使用QWen2.5-1.5B-Instruct作为基座模型,中等长度新闻生成绘画指令平均耗时500ms(A100-80G),配合[SGLang](https://github.com/modelscope/sglang)/[vllm](https://github.com/vllm-project/vllm)等框架可以更快的生成绘画指令。 | |
| ## 快速开始 | |
| ### 🤗 Hugging Face Transformers | |
| 使用Transformers生成绘画指令 | |
| ```python | |
| import json | |
| from transformers import AutoModelForCausalLM, AutoTokenizer | |
| model_name = "blacker521/NewsPicGen" | |
| model = AutoModelForCausalLM.from_pretrained( | |
| model_name, | |
| torch_dtype="auto", | |
| device_map="auto" | |
| ) | |
| tokenizer = AutoTokenizer.from_pretrained(model_name) | |
| title = "孙颖莎谈大满贯最大的挑战" | |
| content = "#孙颖莎希望找到赛场上拼搏的状态# 9月24日,是WTT中国大满贯2024倒计时2天,球员@孙颖莎 接受专访。孙颖莎在采访中谈及大满贯中最大的挑战,她表示大满贯已经是很顶尖的赛事水平了,所以每场球都会有挑战,希望自己能找到积极专注的在赛场上拼搏的状态。" | |
| prompt = f'以下是一篇新闻,标题“{title}”。新闻内容:{content},请根据新闻内容生成绘画指令,图片要符合新闻内容,并且有创意。' | |
| messages = [ | |
| {"role": "user", "content": prompt} | |
| ] | |
| text = tokenizer.apply_chat_template( | |
| messages, | |
| tokenize=False, | |
| add_generation_prompt=True | |
| ) | |
| model_inputs = tokenizer([text], return_tensors="pt").to(model.device) | |
| generated_ids = model.generate( | |
| **model_inputs, | |
| max_new_tokens=512 | |
| ) | |
| generated_ids = [ | |
| output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids) | |
| ] | |
| response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0] | |
| print(json.dumps(response, ensure_ascii=False)) | |
