torchvision.models.densenet201(*, weights: Optional[DenseNet201_Weights] = None, progress: bool = True, **kwargs: Any) DenseNet[source]

Densenet-201 model from Densely Connected Convolutional Networks.

Parameters:
  • weights (DenseNet201_Weights, optional) – The pretrained weights to use. See DenseNet201_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.DenseNet201_Weights(value)[source]

The model builder above accepts the following values as the weights parameter. DenseNet201_Weights.DEFAULT is equivalent to DenseNet201_Weights.IMAGENET1K_V1. You can also use strings, e.g. weights='DEFAULT' or weights='IMAGENET1K_V1'.

DenseNet201_Weights.IMAGENET1K_V1:

These weights are ported from LuaTorch. Also available as DenseNet201_Weights.DEFAULT.

The inference transforms are available at DenseNet201_Weights.IMAGENET1K_V1.transforms and perform the following preprocessing operations: Accepts PIL.Image, batched (B, C, H, W) and single (C, H, W) image torch.Tensor objects. The images are resized to resize_size=[256] using interpolation=InterpolationMode.BILINEAR, followed by a central crop of crop_size=[224]. Finally the values are first rescaled to [0.0, 1.0] and then normalized using mean=[0.485, 0.456, 0.406] and std=[0.229, 0.224, 0.225].
