# AF3AD Checkpoints

Pretrained AF3AD PO3AD-style checkpoints for Real3D-AD and AnomalyShapeNet.

Each checkpoint is packaged with a small YAML config per category.

The current AnomalyShapeNet release includes 37 categories; the remaining categories will be added later.

## Usage

Clone or download this repository into the project as `ckpts/`:

```text
ckpts/Real3DAD/[category]/ckpts/[category].pth
ckpts/Real3DAD/[category]/po3ad_eval_real3d.yaml
ckpts/AnomalyShapeNet/[category]/ckpts/[category].pth
ckpts/AnomalyShapeNet/[category]/po3ad_eval_anomalyshapenet.yaml
```

From the AF3AD repo root:

```bash
export PYTHONPATH="$PWD:$PYTHONPATH"
python3 scripts/evaluate_po3ad_checkpoint.py --checkpoint ckpts/Real3DAD/airplane/ckpts/airplane.pth --config ckpts/Real3DAD/airplane/po3ad_eval_real3d.yaml
python3 scripts/evaluate_po3ad_checkpoint.py --checkpoint ckpts/AnomalyShapeNet/ashtray0/ckpts/ashtray0.pth --config ckpts/AnomalyShapeNet/ashtray0/po3ad_eval_anomalyshapenet.yaml
```

Replace `airplane` or `ashtray0` with any available category from the matching dataset.

To evaluate all currently packaged AnomalyShapeNet categories:

```bash
bash ckpts/AnomalyShapeNet/eval_commands.sh
```
