#  vit_large_patch16_224.swag_lin

A [Vision Transformer](https://arxiv.org/abs/2010.11929v2) image classification model. Weights are learned with [SWAG](https://arxiv.org/abs/2201.08371) on ImageNet-1k data.

Disclaimer: This is a porting of the torchvision model weights to Apple MLX Framework.


## How to use
```bash
pip install mlx-image
```

Here is how to use this model for image classification:

```python
from mlxim.model import create_model
from mlxim.io import read_rgb
from mlxim.transform import ImageNetTransform

transform = ImageNetTransform(train=False, img_size=224)
x = transform(read_rgb("cat.png"))
x = mx.expand_dims(x, 0)

model = create_model("vit_large_patch16_224.swag_lin")
model.eval()

logits = model(x)
```

You can also use the embeds from layer before head:
```python
from mlxim.model import create_model
from mlxim.io import read_rgb
from mlxim.transform import ImageNetTransform

transform = ImageNetTransform(train=False, img_size=224)
x = transform(read_rgb("cat.png"))
x = mx.expand_dims(x, 0)

# first option
model = create_model("vit_large_patch16_224.swag_lin", num_classes=0)
model.eval()

embeds = model(x)

# second option
model = create_model("vit_large_patch16_224.swag_lin")
model.eval()

embeds = model.get_features(x)
```
