efficientnet_b6_cls(pretrained: bool | str = False, weights: EfficientNetB6Weights | None = None, overrides: object = {})EfficientNet-B6 image classifier (backbone + GAP + linear head).
Builds an EfficientNetForImageClassification with the
B6 compound-scaling configuration (width × 1.8, depth × 2.6)
followed by dropout () and a linear classifier.
Approximately 43M parameters and 84.0% ImageNet-1k top-1
accuracy at 528×528 (Tan & Le, 2019, Table 2).

Parameters
pretrainedbool or str= FalsePretrained-weight selector.
False → random init; True
→ the DEFAULT tag
(EfficientNetB6Weights.IMAGENET1K_V1); a tag string →
that specific checkpoint. Mutually exclusive with weights.Explicit weights enum member. Takes precedence over

EfficientNetConfig.Returns
EfficientNetForImageClassificationClassifier with the B6 configuration applied (or with
overrides merged on top of it), optionally initialised from
pretrained weights.
Notes
See Tan & Le, "EfficientNet: Rethinking Model Scaling for
Convolutional Neural Networks", ICML 2019 (arXiv:1905.11946),
Table 2. Pretrained weights are converted from the
reference-framework EfficientNet_B6_Weights and hosted under
lucid-dl/efficientnet-b6.
