mobilenet_v3_large

torchvision.models.mobilenet_v3_large(*, weights: Optional[torchvision.models.mobilenetv3.MobileNet_V3_Large_Weights] = None, progress: bool = True, **kwargs: Any) → torchvision.models.mobilenetv3.MobileNetV3

Constructs a large MobileNetV3 architecture from Searching for MobileNetV3.

Parameters

• weights (MobileNet_V3_Large_Weights, optional) – The pretrained weights to use. See MobileNet_V3_Large_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.resnet.MobileNetV3 base class. Please refer to the source code for more details about this class.

class torchvision.models.MobileNet_V3_Large_Weights(value)

The model builder above accepts the following values as the weights parameter. MobileNet_V3_Large_Weights.DEFAULT is equivalent to MobileNet_V3_Large_Weights.IMAGENET1K_V2. You can also use strings, e.g. weights='DEFAULT' or weights='IMAGENET1K_V1'.

MobileNet_V3_Large_Weights.IMAGENET1K_V1:

These weights were trained from scratch by using a simple training recipe.

acc@1 (on ImageNet-1K)	74.042
acc@5 (on ImageNet-1K)	91.34
min_size	height=1, width=1
categories	tench, goldfish, great white shark, … (997 omitted)
num_params	5483032
recipe	link

The inference transforms are available at MobileNet_V3_Large_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].

MobileNet_V3_Large_Weights.IMAGENET1K_V2:

These weights improve marginally upon the results of the original paper by using a modified version of TorchVision’s new training recipe. Also available as MobileNet_V3_Large_Weights.DEFAULT.
