library_name: keras-hub
This is a DenseNet model uploaded using the KerasHub library and can be used with JAX, TensorFlow, and PyTorch backends.
This model is related to an ImageClassifier task.
DenseNet is a convolution network which densely connects each layer to every other layer in a feed-forward fashion. The model was originally evaluated on four object recognition benchmark tasks (CIFAR-10, CIFAR-100, SVHN, and ImageNet). See the model card below for benchmarks, data sources, and intended use cases. This model is supported in both KerasCV and KerasHub. KerasCV will no longer be actively developed, so please try to use KerasHub.

Installation
Keras and KerasHub can be installed with:
pip install -U -q keras-hub
pip install -U -q keras
Jax, TensorFlow, and Torch come preinstalled in Kaggle Notebooks. For instructions on installing them in another environment see the Keras Getting Started page.

Example Use
input_data = np.ones(shape=(8, 224, 224, 3))
# Pretrained backbone
model = keras_hub.models.DenseNetBackbone.from_preset("hf://keras/densenet_201_imagenet")
model(input_data)
# Randomly initialized backbone with a custom config
model = keras_hub.models.DenseNetBackbone(
stackwise_num_repeats=[6, 12, 24, 16],
)
model(input_data)
# Use densenet for image classification task
model = keras_hub.models.ImageClassifier.from_preset("hf://keras/densenet_201_imagenet")
# User Timm presets directly from HuggingFace
model = keras_hub.models.ImageClassifier.from_preset('hf://timm/densenet201.tv_in1k')
