vgg_19_cls(pretrained: bool | str = False, weights: VGG19Weights | None = None, overrides: object = {})VGG-19 image classifier (config E, no BatchNorm).
Builds a VGGForImageClassification with the paper-cited
VGG-19 topology (arch=(2, 2, 4, 4, 4)) followed by the standard
4096 → 4096 → num_classes FC head. Approximately 143.7 M
parameters total. Reaches a top-1 ImageNet validation accuracy of
72.38% (torchvision eval).
Model Size
Parameters
pretrainedbool or str= FalsePretrained-weight selector.
False → random init; True
→ the DEFAULT tag (VGG19Weights.IMAGENET1K_V1); a
tag string → that specific checkpoint. Mutually exclusive with
weights (which wins if both are given).Explicit weights enum member. Takes precedence over
pretrained.**overridesobject= {}Keyword overrides forwarded into
VGGConfig.Returns
VGGForImageClassificationClassifier with the VGG-19 configuration applied (or with
overrides merged on top of it), optionally initialised from
pretrained weights.
Notes
Pretrained weights are converted from torchvision's VGG19_Weights
and hosted on the Hugging Face Hub under lucid-dl/vgg-19.

>>> model = vgg_19_cls(pretrained=True)
>>> x = lucid.randn(1, 3, 224, 224)
