shufflenet_v2_x1_5

torchvision.models.shufflenet_v2_x1_5(*, weights: Optional[ShuffleNet_V2_X1_5_Weights] = None, progress: bool = True, **kwargs: Any) → ShuffleNetV2

Constructs a ShuffleNetV2 architecture with 1.5x output channels, as described in ShuffleNet V2: Practical Guidelines for Efficient CNN Architecture Design.

Parameters:

• weights (ShuffleNet_V2_X1_5_Weights, optional) – The pretrained weights to use. See ShuffleNet_V2_X1_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.shufflenetv2.ShuffleNetV2 base class. Please refer to the source code for more details about this class.

class torchvision.models.ShuffleNet_V2_X1_5_Weights(value)

The model builder above accepts the following values as the weights parameter. ShuffleNet_V2_X1_5_Weights.DEFAULT is equivalent to ShuffleNet_V2_X1_5_Weights.IMAGENET1K_V1. You can also use strings, e.g. weights='DEFAULT' or weights='IMAGENET1K_V1'.

ShuffleNet_V2_X1_5_Weights.IMAGENET1K_V1:

These weights were trained from scratch by using TorchVision’s new training recipe. Also available as ShuffleNet_V2_X1_5_Weights.DEFAULT.

The inference transforms are available at ShuffleNet_V2_X1_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=[232] 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].
