## SAVRN's Notes on vit_tiny_patch16_224.augreg_in21k_ft_in1k

ViT Tiny is the smallest standard vision transformer, 6M parameters, trained on ImageNet-21K and fine-tuned on ImageNet-1K. It runs on phones and CPUs.

Apache 2.0 allows commercial use. It is useful as a fast baseline, a teacher-student target, or a classifier where latency matters more than accuracy. Test EdgeNeXt small as an alternative for edge devices.

```
from urllib.request import urlopen
from PIL import Image
import timm

img = Image.open(urlopen(

model = timm.create_model('vit_tiny_patch16_224.augreg_in21k_ft_in1k', pretrained=True)
model = model.eval()

# get model specific transforms (normalization, resize)
data_config = timm.data.resolve_model_data_config(model)
transforms = timm.data.create_transform(**data_config, is_training=False)

output = model(transforms(img).unsqueeze(0))  # unsqueeze single image into batch of 1

top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)
