swin_s¶
- torchvision.models.swin_s(*, weights: Optional[Swin_S_Weights] = None, progress: bool = True, **kwargs: Any) SwinTransformer [source]¶
Constructs a swin_small architecture from Swin Transformer: Hierarchical Vision Transformer using Shifted Windows.
- Parameters:
weights (
Swin_S_Weights
, optional) – The pretrained weights to use. SeeSwin_S_Weights
below for more details, and possible values. By default, no pre-trained weights are used.progress (bool, optional) – If True, displays a progress bar of the download to stderr. Default is True.
**kwargs – parameters passed to the
torchvision.models.swin_transformer.SwinTransformer
base class. Please refer to the source code for more details about this class.
- class torchvision.models.Swin_S_Weights(value)[source]¶
The model builder above accepts the following values as the
weights
parameter.Swin_S_Weights.DEFAULT
is equivalent toSwin_S_Weights.IMAGENET1K_V1
. You can also use strings, e.g.weights='DEFAULT'
orweights='IMAGENET1K_V1'
.Swin_S_Weights.IMAGENET1K_V1:
These weights reproduce closely the results of the paper using a similar training recipe. Also available as
Swin_S_Weights.DEFAULT

recipe
The inference transforms are available at
Swin_S_Weights.IMAGENET1K_V1.transforms
and perform the following preprocessing operations: AcceptsPIL.Image
, batched(B, C, H, W)
and single(C, H, W)
imagetorch.Tensor
objects. The images are resized toresize_size=[246]
usinginterpolation=InterpolationMode.BICUBIC
, followed by a central crop ofcrop_size=[224]
. Finally the values are first rescaled to[0.0, 1.0]
and then normalized usingmean=[0.485, 0.456, 0.406]
andstd=[0.229, 0.224, 0.225]
