## Pretrained Models

Latency/Throughput is measured on NVIDIA Jetson AGX Orin, and NVIDIA A100 GPU with TensorRT, fp16. Data transfer time is included.

## Usage

```python
# segment anything
from efficientvit.sam_model_zoo import create_sam_model

efficientvit_sam = create_sam_model(
  name="xl1", weight_url="assets/checkpoints/sam/xl1.pt",
)
efficientvit_sam = efficientvit_sam.cuda().eval()
```

```python
from efficientvit.models.efficientvit.sam import EfficientViTSamPredictor

efficientvit_sam_predictor = EfficientViTSamPredictor(efficientvit_sam)
```

```python
from efficientvit.models.efficientvit.sam import EfficientViTSamAutomaticMaskGenerator

efficientvit_mask_generator = EfficientViTSamAutomaticMaskGenerator(efficientvit_sam)

```
