depth Depth of ResNet network.
input_shape optional shape tuple. It should have exactly 3 inputs channels, and width and height should be no smaller than 32. E.g. (200, 200, 3) would be one valid value.
bn_momentum Momentum parameter for Batch Normalization layers.
bn_epsilon Epsilon parameter for Batch Normalization layers.
activation activation function.
se_ratio Squeeze and Excitation layer ratio.
dropout_rate dropout rate before final classifier layer.
drop_connect_rate dropout rate at skip connections.
include_top whether to include the fully-connected layer at the top of the network.
block_args list of dicts, parameters to construct block modules.
model_name name of the model.
pooling optional pooling mode for feature extraction when include_top is False.

  • 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.
weights one of None (random initialization), 'imagenet' (pre-training on ImageNet), or the path to the weights file to be loaded. Note: one model can have multiple imagenet variants depending on input shape it was trained with. For input_shape 224x224 pass imagenet-i224 as argument. By default, highest input shape weights are downloaded.
input_tensor optional Keras tensor (i.e. output of layers.Input()) to use as image input for the model.
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.
classifier_activation A str 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.
include_preprocessing Boolean, whether to include the preprocessing layer (Rescaling) at the bottom of the network. Note: Input image is normalized by ImageNet mean and standard deviation. Defaults to True.
