## Environment
Git clone our repository, creating a python environment and activate it via the following command: 
```bash
conda create -n fsfm3c python=3.9
conda activate fsfm3c
pip install -r requirements.txt
```

## Model Loading
```python
import models_vit
from huggingface_hub import hf_hub_download
CKPT_SAVE_PATH = [your checkpoint storage path]
CKPT_NAME = [checkpoint name]
hf_hub_download(local_dir=CKPT_SAVE_PATH,
                repo_id='Wolowolo/fsfm-3c',
                filename=CKPT_NAME)
model = models_vit.__dict__['vit_base_patch16'](
    num_classes=2,
    drop_path_rate=0.1,
    global_pool=True,
)
checkpoint = torch.load(os.path.join(CKPT_SAVE_PATH, CKPT_NAME), map_location='cpu')
model.load_state_dict(checkpoint['model'])
```

## Downstream Use
Face security tasks such as deepfake detection, face anti-spoofing, and diffusion facial forgery detection.
