densenet161¶
- torchvision.models.densenet161(*, weights: Optional[DenseNet161_Weights] = None, progress: bool = True, **kwargs: Any) DenseNet [source]¶
Densenet-161 model from Densely Connected Convolutional Networks.
- Parameters:
weights (
DenseNet161_Weights
, optional) – The pretrained weights to use. SeeDenseNet161_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.densenet.DenseNet
base class. Please refer to the source code for more details about this class.
- class torchvision.models.DenseNet161_Weights(value)[source]¶
The model builder above accepts the following values as the
weights
parameter.DenseNet161_Weights.DEFAULT
is equivalent toDenseNet161_Weights.IMAGENET1K_V1
. You can also use strings, e.g.weights='DEFAULT'
orweights='IMAGENET1K_V1'
.DenseNet161_Weights.IMAGENET1K_V1:
These weights are ported from LuaTorch. Also available as
DenseNet161_Weights.DEFAULT

The inference transforms are available at
DenseNet161_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=[256]
usinginterpolation=InterpolationMode.BILINEAR
, 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]
