vgg11

torchvision.models.vgg11(*, weights: Optional[VGG11_Weights] = None, progress: bool = True, **kwargs: Any) → VGG

VGG-11 from Very Deep Convolutional Networks for Large-Scale Image Recognition.

Parameters:

• weights (VGG11_Weights, optional) – The pretrained weights to use. See VGG11_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.vgg.VGG base class. Please refer to the source code for more details about this class.

class torchvision.models.VGG11_Weights(value)

The model builder above accepts the following values as the weights parameter. VGG11_Weights.DEFAULT is equivalent to VGG11_Weights.IMAGENET1K_V1. You can also use strings, e.g. weights='DEFAULT' or weights='IMAGENET1K_V1'.

VGG11_Weights.IMAGENET1K_V1:

These weights were trained from scratch by using a simplified training recipe. Also available as VGG11_Weights.DEFAULT.

The inference transforms are available at VGG11_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].
