# About **ULTIMA-YOLO** models
This is a part of [ULTIMA](https://huggingface.co/datasets/UmaDiffusion/ULTIMA) project.
ULTIMA is **U**ma Musume **L**abeled **T**ext-**I**mage **M**ultimodal **A**lignment.
ULTIMA-YOLOv9 model is a facial detection model for Uma Musumes in illustrations and based on [yolov9](https://arxiv.org/abs/2402.13616)-e and [ULTIMA-YOLO dataset](https://huggingface.co/datasets/UmaDiffusion/ULTIMA-YOLO)
This is the model repository for ULTIMA-YOLOv9, containing the following checkpoints:
- YOLO9-E
### How to Use
Clone YOLOv9 repository.
```
git clone https://github.com/WongKinYiu/yolov9.git
cd yolov9
```
Download the weights using `hf_hub_download` and use the loading function in helpers of YOLOv9.
```python
from huggingface_hub import hf_hub_download
hf_hub_download("UmaDiffusion/ULTIMA-YOLOv9", filename="ultima_yolov9-e.pt", local_dir="./")
```
Load the model.
```python
# make sure you have the following dependencies
import torch
import numpy as np
from models.common import DetectMultiBackend
from utils.general import non_max_suppression, scale_boxes
from utils.torch_utils import select_device, smart_inference_mode
from utils.augmentations import letterbox
import PIL.Image
@smart_inference_mode()
def predict(image_path, weights='ultima_yolov9-e.pt', imgsz=640, conf_thres=0.1, iou_thres=0.45):
# Initialize
device = select_device('0')
model = DetectMultiBackend(weights=weights, device=device, fp16=False)
stride, names, pt = model.stride, model.names, model.pt
# Load image
image = np.array(PIL.Image.open(image_path).convert("RGB"))
img = letterbox(image, imgsz, stride=stride, auto=True)[0]
img = img.transpose(2, 0, 1)
img = np.ascontiguousarray(img)
img = torch.from_numpy(img).to(device).float()
img /= 255.0
if img.ndimension() == 3:
img = img.unsqueeze(0)
# Inference
pred = model(img, augment=False, visualize=False)
# Apply NMS
pred = non_max_suppression(pred[0][0], conf_thres, iou_thres, classes=None, max_det=1000)
```
or use `detect.py` in yolov9 repo.
```bash
python ./detect.py --source [image_path] --device 0 --img 1280 --weights './ultima_yolov9-e.pt' --name ultima_yolov9_1280_detect
```
