LibreSwint-cls

Swin Transformer V1 Tiny image classifier (224px input, ImageNet-1k, 1,000 classes), repackaged for LibreYOLO. 28,288,354 parameters.

Source

Derived from the Microsoft Research Swin Transformer V1 release at commit f82860bfb5225915aca09c3227159ee9e1df874d, with released weight storage at SwinTransformer/storage v1.0.0 (commit 3cc359915d3a6079b176a871f68d5fb0d8dfdea2). Copyright (c) 2021 SwinTransformer. Licensed under the MIT License.

The exact source snapshot is timm/swin_tiny_patch4_window7_224.ms_in1k at revision 4cc3a7275b50b53a7bec45f32c236ebe64227cff. Its model.safetensors SHA-256 is fb01861f793143135fa0d6cd97b1631e4b33eaa3ee162bbea9e62de1c76ebac1. Training lineage: ImageNet-1k.

The Apache-2.0 timm v1.0.28 implementation at commit 8ef73809f622e0031bd7f4940265734aef8b9978 is the architecture and parity reference; it does not relicense the MIT weight release.

Modifications

Learned parameters are unchanged. The checkpoint is metadata-wrapped into the LibreYOLO schema with canonical ImageNet-1k class names. LibreYOLO's native Swin V1 implementation matches timm's parameter names and produces bit-exact pretrained logits (max_abs_diff == 0). The converted checkpoint SHA-256 is 81844e9bbe8edba1d0e0c204341126d2ed77fd0905eb96aec1fad188c02c71fe.

Usage

from libreyolo import LibreYOLO

model = LibreYOLO("LibreSwint-cls.pt")
result = model.predict("image.jpg")[0]
print(result.probs.top1, result.probs.top5)
