In recent years, the development of diffusion models is very rapid, but I found that the current evaluation metrics on diffusion models are not well integrated. Therefore, I refer to the market for some of the more standard code for calculating diffusion metrics, and built a pipeline code base for integrating several evaluation metrics of diffusion models. Welcome to star + fork.

We will also update some other metrics, and tensorflow integration pipeline, may also add T2V series, please look forward to!

pip install -r requirements.txt

conda env create -f environment.yaml

• Install PyTorch:

pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116  # Choose a version that suits your GPU

• Install Scipy

pip install scipy

• Install CLIP:

pip install git+https://github.com/openai/CLIP.git

You need to download the inception_v3_google.pth, pt_inception.pth, and ViT-B-32.pt weights files and place them in the checkpoints folder. We have integrated them into the following links for your convenience.

We provide a simple script for quickly computing an integrated pipeline on several metrics of diffusion models.

bash scripts/start.sh

You can also run the following command directly from the command line to calculate metrics.

# for img-txt
python ./cal_diffusion_metric.py  --cal_IS --cal_FID --cal_CLIP \
    --path1 ./examples/imgs1 --path2 ./examples/imgs2 \
    --real_path ./examples/imgs1 --fake_path ./examples/prompt
# for jsonl
python ./cal_diffusion_metric.py  --cal_IS --cal_FID --cal_CLIP \
    --path1 ./examples/imgs1 --path2 ./examples/imgs2 \
    --jsonl_path .examples/img-txt.jsonl # for img-txt

where --cal_IS indicates whether to calculate IS, --cal_FID indicates whether to calculate FID, and --cal_CLIP indicates whether to calculate CLIP.

Where --path1 denotes the path of the generated image when calculating FID, and --path2 denotes the path of the real image when calculating FID. Calculate IS will use --path1 by default.

Where --real_path denotes the path to the real image used to compute the clip score, and --fake_path denotes the path to the text used to compute the clip score. Passing in a single --jsonl_path is also supported, with the jsonl format taking precedence.
