The model corresponds to [Compare2Score](https://compare2score.github.io/).

## Quick Start with AutoModel

<!-- For this image, ![](https://raw.githubusercontent.com/Q-Future/Q-Align/main/fig/singapore_flyer.jpg) start an AutoModel scorer with `transformers==4.36.1`:
 -->
```python
import requests
import torch
from transformers import AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained("q-future/Compare2Score", trust_remote_code=True, attn_implementation="eager", 
                                             torch_dtype=torch.float16, device_map="auto")

from PIL import Image
image_path_url = "https://raw.githubusercontent.com/Q-Future/Q-Align/main/fig/singapore_flyer.jpg"
print("The quality score of this image is {}".format(model.score(image_path_url)) 
```

## Evaluation with GitHub
```shell
git clone https://github.com/Q-Future/Compare2Score.git
cd Compare2Score
pip install -e .
```

```python
from q_align import Compare2Scorer
from PIL import Image

scorer = Compare2Scorer()
image_path = "figs/i04_03_4.bmp"
print("The quality score of this image is {}.".format(scorer(image_path)))
```
