  • in_channels (int) – Number of input channels.

  • loss (nn.Module) – Training loss.

  • optim_recipe (Any) – optimization recipe, corresponds to what expect the LightningModule.configure_optimizers() method.

  • version (str) –

    Determines which ResNet version to use:

    • "std": original ResNet

    • "packed": Packed-Ensembles ResNet

    • "batched": BatchEnsemble ResNet

    • "masked": Masksemble ResNet

    • "mimo": MIMO ResNet

    • "mc-dropout": Monte-Carlo Dropout ResNet

  • arch (int) –

    Determines which ResNet architecture to use:

    • 18: ResNet-18

    • 32: ResNet-32

    • 50: ResNet-50

  • imagenet.

  • normalization_layer (type[nn.Module], optional) – Normalization layer to use. Defaults to nn.BatchNorm2d.

  • num_estimators (int, optional) – Number of estimators in the ensemble. Only used if version is either "packed", "batched", "masked" or "mc-dropout" Defaults to None.

  • dropout_rate (float, optional) – Dropout rate. Defaults to 0.0.

  • mixup_params (dict, optional) – Mixup parameters. Can include mixtype, mixmode, dist_sim, kernel_tau_max, kernel_tau_std, mixup_alpha, and cutmix_alpha. If None, no augmentations. Defaults to None.

  • groups – Number of groups in convolutions. Defaults to 1.

  • scale – Expansion factor affecting the width of the estimators. Only used if version is "masked". Defaults to None.

  • alpha (float, optional) – Expansion factor affecting the width of the estimators. Only used if version is "packed". Defaults to None.

  • gamma (int, optional) – Number of groups within each estimator. Only used if version is "packed" and scales with groups. Defaults to 1.

  • rho (float, optional) – Probability that all estimators share the same input. Only used if version is "mimo". Defaults to 1.

  • batch_repeat (int, optional) – Number of times to repeat the batch. Only used if version is "mimo". Defaults to 1.

  • ood_criterion (str, optional) – OOD criterion. Defaults to "msp". MSP is the maximum softmax probability, logit is the maximum logit, entropy is the entropy of the mean prediction, mi is the mutual information of the ensemble and vr is the variation ratio of the ensemble.
