## Usage

### PyTorch
```python
from huggingface_hub import hf_hub_download
import torch

# Download checkpoint
ckpt_path = hf_hub_download("carpedm20/DEIMv2", "deimv2_dinov3_s_coco.pth")
checkpoint = torch.load(ckpt_path, map_location='cpu')
state_dict = checkpoint['ema']['module']
```

### ONNX Runtime
```python
import onnxruntime as ort
from huggingface_hub import hf_hub_download

onnx_path = hf_hub_download("carpedm20/DEIMv2", "deimv2_dinov3_s_coco.onnx")
session = ort.InferenceSession(onnx_path)
```

### TensorRT
```python
import tensorrt as trt
from huggingface_hub import hf_hub_download

engine_path = hf_hub_download("carpedm20/DEIMv2", "deimv2_dinov3_s_coco.engine")
# Load engine with TensorRT runtime
```
