Install

1. Clone this repository and navigate to EvalAlign folder

git clone https://github.com/SAIS-FUXI/EvalAlign.git
cd EvalAlign

2. Install Package

conda create -n evalalign python=3.10 -y
conda activate evalalign
pip install --upgrade pip 
pip install -e .

EvalAlign Weights

Please download the Model weight from huggingface.

Image Faithfulness evaluation

You must use the prompt provide about faithfulness to generate some images on your own model or open source model.The file name of the image needs to be consistent with prompt_id.

  {
    "prompt_id": "259_2_2",
    "prompt": "A young man was painting a beautiful landscape with a yellow brush and a black canvas."
  }

For example, in this data, you generated an image using prompt and named it "259_2_2. jpg".

#Run script
./scripts/inference_faithfulness.sh

You need to modify the path in the script

CUDA_VISIBLE_DEVICES=0 python evalalign/eval/test_faithfulness.py \
    --model-path Fudan-FUXI/evalalign-v1.0-13b \ # Downloaded model weights
    --images-dir ./PixArt-XL-2-1024-MS \  # The folder for generating images
    --output-dir ./results_faithfulness 

• result faithfulness

You will get a body, hand，face，object, common, The scores of the five dimensions and the average score of the overall model

Text-to-Image Alignment evaluation

Same as Faithfulness.You must use the prompt provide about faithfulness to generate some images on your own model or open source model.The file name of the image needs to be consistent with prompt_id.

  {
    "prompt_id": "99",
    "prompt": "two refrigerators stand side-by-side in a kitchen, with two potted plants on either side of them."
  }

For example, in this data, you generated an image using prompt and named it "99. jpg".

#Run script
./scripts/inference_alignment.sh

You need to modify the path in the script

CUDA_VISIBLE_DEVICES=0 python evalalign/eval/test_faithfulness.py \
    --model-path Fudan-FUXI/evalalign-v1.0-13b \ # Downloaded model weights
    --images-dir ./IF-I-XL-v1.0 \  # The folder for generating images
    --output-dir ./results_alignment 

• result faithfulness You will get a Object, Count，Spatial，Action, Color, Style.The scores of the six dimensions and the average score of the overall model.

  "Object_score": 209,
  "Object_num": 118,
