torchvision.models.mnasnet0_5(*, weights: Optional[torchvision.models.mnasnet.MNASNet0_5_Weights] = None, progress: bool = True, **kwargs: Any) → torchvision.models.mnasnet.MNASNet

MNASNet with depth multiplier of 0.5 from MnasNet: Platform-Aware Neural Architecture Search for Mobile paper.

Parameters

• weights (MNASNet0_5_Weights, optional) – The pretrained weights to use. See MNASNet0_5_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.mnasnet.MNASNet base class. Please refer to the source code for more details about this class.

class torchvision.models.MNASNet0_5_Weights(value)

The model builder above accepts the following values as the weights parameter. MNASNet0_5_Weights.DEFAULT is equivalent to MNASNet0_5_Weights.IMAGENET1K_V1. You can also use strings, e.g. weights='DEFAULT' or weights='IMAGENET1K_V1'.

MNASNet0_5_Weights.IMAGENET1K_V1:

These weights reproduce closely the results of the paper. Also available as MNASNet0_5_Weights.DEFAULT.

acc@1 (on ImageNet-1K)	67.734
acc@5 (on ImageNet-1K)	87.49

The inference transforms are available at MNASNet0_5_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].
