Swin-Tiny

Liu et al., 2021 — Swin Transformer: Hierarchical Vision Transformer using Shifted Windows (arXiv:2103.14030)

Lucid port of torchvision/Swin_T_Weights.IMAGENET1K_V1, converted to Lucid-native safetensors.

Available weights

Tag	acc@1	acc@5	Params	GFLOPs	Size	Source
IMAGENET1K_V1 (default)	81.474	95.776	28.3M	4.491	107.93 MB	torchvision

Usage

import lucid.models as models
from lucid.models.weights import SwinTinyWeights

# default tag
model = models.swin_tiny_cls(pretrained=True)

# explicit tag (enum or string)
model = models.swin_tiny_cls(weights=SwinTinyWeights.IMAGENET1K_V1)
model = models.swin_tiny_cls(pretrained="IMAGENET1K_V1")

# preprocessing travels with the weights
weights = SwinTinyWeights.IMAGENET1K_V1
preprocess = weights.transforms()
logits = model(preprocess(image)[None]).logits

Conversion

Converted from torchvision/Swin_T_Weights.IMAGENET1K_V1 via python -m tools.convert_weights swin_tiny --tag IMAGENET1K_V1. Key mapping + numerical parity verified against the source.
