Arguments

Arguments Description
blocks numbers of building blocks for the four dense layers.
include_top whether to include the fully-connected layer at the top of the network.
weights one of NULL (random initialization), ‘imagenet’ (pre-training on ImageNet), or the path to the weights file to be loaded.
input_tensor optional Keras tensor (i.e. output of layer_input()) to use as image input for the model.
input_shape optional shape list, only to be specified if include_top is FALSE (otherwise the input shape has to be (224, 224, 3) (with channels_last data format) or (3, 224, 224) (with channels_first data format). It should have exactly 3 inputs channels.
pooling optional pooling mode for feature extraction when include_top is FALSE. - NULL 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.
x a 3D or 4D array consists of RGB values within [0, 255].
data_format data format of the image tensor.

Details

Optionally loads weights pre-trained on ImageNet. Note that when using TensorFlow, for best performance you should set image_data_format='channels_last' in your Keras config at ~/.keras/keras.json. The model and the weights are compatible with TensorFlow, Theano, and CNTK. The data format convention used by the model is the one specified in your Keras config file.
