Boolean, whether to include the fully-connected
layer at the top of the network. Defaults to True.
weights
One of None (random initialization),
"imagenet" (pre-training on ImageNet),
or the path to the weights file to be loaded. Defaults to "imagenet".
input_tensor
Optional Keras tensor
(i.e. output of layers.Input())
to use as image input for the model.
input_shape
Optional shape tuple, only to be specified
if include_top is False.
It should have exactly 3 inputs channels.
pooling
Optional pooling mode for feature extraction
when include_top is False. Defaults to None.
None means that the output of the model will be
the 4D tensor output of the
last convolutional layer.
"avg" means that global average pooling
will be applied to the output of the
last convolutional layer, and thus
the output of the model will be a 2D tensor.
"max" means that global max pooling will
be applied.
classes
Optional number of classes to classify images
into, only to be specified if include_top is True, and
if no weights argument is specified. Defaults to 1000 (number of
ImageNet classes).
classifier_activation
A string or callable. The activation function to use
on the "top" layer. Ignored unless include_top=True. Set
classifier_activation=None to return the logits of the "top" layer.
Defaults to "softmax".
When loading pretrained weights, classifier_activation can only
be None or "softmax".

For EfficientNetV2, by default input preprocessing is included as a part of the model (as a `Rescaling` layer), and thus [`keras.applications.efficientnet_v2.preprocess_input`](../../../tf/keras/applications/efficientnet_v2/preprocess_input) is actually a pass-through function. In this use case, EfficientNetV2 models expect their inputs to be float tensors of pixels with values in the `[0, 255]` range. At the same time, preprocessing as a part of the model (i.e. `Rescaling` layer) can be disabled by setting `include_preprocessing` argument to `False`. With preprocessing disabled EfficientNetV2 models expect their inputs to be float tensors of pixels with values in the `[-1, 1]` range.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n| Args ---- ||\n|-------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `include_top` | Boolean, whether to include the fully-connected layer at the top of the network.
