(*, weights: Optional[torchvision.models.regnet.RegNet_X_3_2GF_Weights] = None, progress: bool = True, **kwargs: Any) → torchvision.models.regnet.RegNet[source]¶ Constructs a RegNetX_3.2GF architecture from Designing Network Design Spaces.
 Parameters
weights (
RegNet_X_3_2GF_Weights
, optional) – The pretrained weights to use. SeeRegNet_X_3_2GF_Weights
below for more details and possible values. By default, no pretrained weights are used.progress (bool, optional) – If True, displays a progress bar of the download to stderr. Default is True.
**kwargs – parameters passed to either
torchvision.models.regnet.RegNet
ortorchvision.models.regnet.BlockParams
class. Please refer to the source code for more detail about the classes.

RegNet_X_3_2GF_Weights
(value)[source]¶ The model builder above accepts the following values as the
weights
parameter.RegNet_X_3_2GF_Weights.DEFAULT
is equivalent toRegNet_X_3_2GF_Weights.IMAGENET1K_V2
. You can also use strings, e.g.weights='DEFAULT'
orweights='IMAGENET1K_V1'
.RegNet_X_3_2GF_Weights.IMAGENET1K_V1:
These weights reproduce closely the results of the paper using a simple training recipe.

.RegNet_X_3_2GF_Weights.IMAGENET1K_V2:
These weights improve upon the results of the original paper by using a modified version of TorchVision’s new training recipe. Also available as
