# How to use

First, [install mast3r](https://github.com/naver/mast3r?tab=readme-ov-file#installation).
To load the model:

```python
from mast3r.model import AsymmetricMASt3R
import torch

model = AsymmetricMASt3R.from_pretrained("naver/MASt3R_ViTLarge_BaseDecoder_512_catmlpdpt_nonmetric")

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)
```
