**The retrained version on Qwen3.5-VL can be found at [Q-ReAlign](https://github.com/Q-Future/Q-ReAlign)**
## [New Update]
1. We propose the first models (Q-SiT, Q-SiT-mini) that can deal with both image quality scoring and interpreting tasks. See more details [here](https://github.com/Q-Future/Q-SiT).
2. **We release the new version of Q-Align, [Q-ReAlign](https://github.com/Q-Future/Q-ReAlign), which is trained on modern VLMs and gains the same performance with 50% fewer parameters.**
## [Important Note!] v1.1 <-> transformers==4.36.1+
This LLaVA-style repository has been built on `transformers==4.31.0`, which is incompatible with many new models available on Hugging Face. This requires to build a separate environment for the MLLM/LMM repository, which is somewhat troublesome for this **visual scoring** model, as we expect the **Q-Align/OneAlign** to effectively boost other disciplines (image/video generation, *etc*). Both the repository and the **AutoModel** (as follows) are updated to the newest version.
To this end, we have modified respective code for mPLUG-Owl2 to adapt it to the newest transformer version, i.e. `transformers==4.36.1`, so that you do not need to create a separate outdated environment while using it alongside other projects. The updated code is no longer compatible with the old-version Q-Align (v1.0.1/v1.0.0, and before), please update to the newest version via the following scripts:
```shell
git pull
pip install -e .
```
## [Installation Free!] Quicker Start with Hugging Face AutoModel
No need to install this GitHub repo.
```python
import requests
import torch
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("q-future/one-align", trust_remote_code=True,
torch_dtype=torch.float16, device_map="auto")
from PIL import Image
model.score([Image.open(requests.get("https://raw.githubusercontent.com/Q-Future/Q-Align/main/fig/singapore_flyer.jpg",
stream=True).raw)], task_="quality", input_="image") # task_ : quality | aesthetics; # input_: image | video
```
This model also supports to be instantialized via latest [IQA-Pytorch](https://github.com/chaofengc/IQA-PyTorch) (quick install by `pip install git+https://github.com/chaofengc/IQA-PyTorch.git`):
```python
import pyiqa
import torch
qalign = pyiqa.create_metric('qalign').cuda()
quality_score = qalign(input, task_='quality')
aesthetic_score = qalign(input, task_='aesthetic')
```
## Installation
If you only need to infer (or evaluate):
```shell
git clone https://github.com/Q-Future/Q-Align.git
cd Q-Align
pip install -e .
```
For training, you need to further install additional dependencies as follows:
```shell
pip install -e ".[train]"
pip install flash_attn --no-build-isolation
```
## Quick Start
We have fixed the multi-GPU inference problem.
### Image Quality Scorer
- CLI Interface
```shell
export DEFAULT_IMG_PATH=fig/singapore_flyer.jpg
python q_align/evaluate/scorer.py --img_path $DEFAULT_IMG_PATH
```
- Python API
```python
from q_align import QAlignScorer
from PIL import Image
scorer = QAlignScorer()
img_list = [Image.open("fig/singapore_flyer.jpg")] # can be multiple images
print(scorer(img_list).tolist())
```
### Image Aesthetic Scorer
- CLI Interface
```shell
export DEFAULT_IMG_PATH=fig/singapore_flyer.jpg
python q_align/evaluate/scorer.py --img_path $DEFAULT_IMG_PATH --aesthetic --model-path q-future/one-align
```
- Python API
```python
from q_align import QAlignAestheticScorer
from PIL import Image
scorer = QAlignAestheticScorer()
img_list = [Image.open("fig/singapore_flyer.jpg"), Image.open("fig/boy_colorful.png")] # can be multiple images
print(scorer(img_list).tolist())
```
### Video Quality Scorer
- CLI Interface
```shell
export DEFAULT_IMG_PATH=fig/baby.mp4
python q_align/evaluate/scorer.py --img_path $DEFAULT_IMG_PATH --video --model-path q-future/one-align
```
- Python API
```python
from q_align import QAlignVideoScorer, load_video
scorer = QAlignVideoScorer()
video_list = [load_video("fig/baby.mp4")]
print(scorer(video_list).tolist())
```
## Training & Evaluation
### Get Datasets
Download all datasets needed together.
```python
import os, glob
from huggingface_hub import snapshot_download
snapshot_download("q-future/q-align-datasets", repo_type="dataset", local_dir="./playground/data", local_dir_use_symlinks=False)
gz_files = glob.glob("playground/data/*.tar")
for gz_file in gz_files:
print(gz_file)
os.system("tar -xf {} -C ./playground/data/".format(gz_file))
```
For LSVQ, (video quality dataset, optional), you can download as follows:
```python
import os, glob
from huggingface_hub import snapshot_download
snapshot_download("teowu/LSVQ-videos", repo_type="dataset", local_dir="./playground/data/lsvq/", local_dir_use_symlinks=False)
gz_files = glob.glob("playground/data/lsvq/*.tar.gz")
for gz_file in gz_files:
print(gz_file)
os.system("tar -xzf {} -C ./playground/data/lsvq/".format(gz_file))
```
### Evaluation
After preparing the datasets, you can evaluate pre-trained **OneAlign** as follows:
- Image Quality Assessment (IQA)
```shell
python q_align/evaluate/iqa_eval.py --model-path q-future/one-align --device cuda:0
```
- Image Aesthetic Assessment (IAA)
```shell
python q_align/evaluate/iaa_eval.py --model-path q-future/one-align --device cuda:0
```
- Video Quality Assessment (VQA)
```shell
python q_align/evaluate/vqa_eval.py --model-path q-future/one-align --device cuda:0
```
See our [model zoo](./model_zoo) for all available models that you can use.
To convert output logits to scores, you may follow the simplest code below:
```python
import numpy as np
def wa5(logits):
logprobs = np.array([logits["excellent"], logits["good"], logits["fair"], logits["poor"], logits["bad"]])
probs = np.exp(logprobs) / np.sum(np.exp(logprobs))
score = np.inner(probs, np.array([5,4,3,2,1]))
return score
```
