weathon/qwen_2_5_vision_reward

Model Card for neg_aware_qwen

This model is a fine-tuned version of Qwen/Qwen2.5-VL-3B-Instruct. It has been trained using TRL on zai-org/VisionRewardDB-Image. It is aimming for evaluating image's quality similar to VisionReward but with a much smaller and faster model.

Quick start

To use this model, you can just ask the model on an image using one of the dim in VisionReward.

from datasets import load_dataset

# load dataset, you can also use any images
train_ds = load_dataset("zai-org/VisionRewardDB-Image", split='train[:40000]')
test_ds = load_dataset("zai-org/VisionRewardDB-Image", split='train[40000:]')

from transformers import pipeline
pipe = pipeline("image-text-to-text", model="weathon/qwen_2_5_vision_reward")

from transformers import pipeline
import pandas as pd
df = pd.read_csv("rules.csv")
import pandas as pd
import re
from PIL import Image

df.columns = df.columns.str.strip()
df['Dimension'] = df['Dimension'].ffill()

df['dim_key'] = df['Dimension'].apply(lambda x: re.search(r'\((.*?)\)', x).group(1) if re.search(r'\((.*?)\)', x) else x)

guide = {
    dim_key: {
        int(row['Score']): str(row['Description']).strip()
        for _, row in group.iterrows()
    }
    for dim_key, group in df.groupby('dim_key')
}

question = f"You need to rate the quality of an image, guideline: {guide}."

import json
def rate(image):
  messages = [
      {
          "role": "system",
          "content": [{"type": "text", "text": question}],
      },
      {
          "role": "user",
          "content": [
              {
                  "type": "image",
                  "image": image.resize((512, 512)),
              }
          ],
  }]
  gen = pipe(text=messages, return_full_text=False)
  return sum(json.loads(gen[0]["generated_text"].replace("'", '"')).values())

rate(test_ds[3]["image"])

sum(test_ds[3]["annotation"].values())
