Example: Instantiate a stock Xception model

from xception_c import Xception

# Xception from research paper
xception = Xception()

# Xception custom input shape/classes
xception = Xception(input_shape=(128, 128, 3), n_classes=50)

# getter for the tf.keras model
model = xception.model

Example: Compose and Train an Xception model

    ''' Example for constructing/training a Xception model on CIFAR-10
    '''
    # Example of constructing a mini-Xception
    entry  = [{ 'n_filters' : 128 }, { 'n_filters' : 728 }]
    middle = [{ 'n_filters' : 728 }, { 'n_filters' : 728 }, { 'n_filters' : 728 }]

    xception = Xception(entry=entry, middle=middle, input_shape=(32, 32, 3), n_classes=10)
