Can you please help me sorting my error

GRADED FUNCTION
def alpaca_model(image_shape=IMG_SIZE, data_augmentation=data_augmenter()):
‘’’ Define a tf.keras model for binary classification out of the MobileNetV2 model
Arguments:
image_shape – Image width and height
data_augmentation – data augmentation function
Returns:
Returns:
tf.keras.model

input_shape = image_shape + (3,)
### START CODE HERE
base_model = tf.keras.applications.MobileNetV2(input_shape=input_shape,
include_top=False, # <== Important!!!!
weights='imagenet') # From imageNet
# freeze the base model by making it non trainable
base_model.trainable = False
# create the input layer (Same as the imageNetv2 input size)
inputs = tfl.Input(shape=input_shape)
# apply data augmentation to the inputs
x = data_augmentation(inputs)
# data preprocessing using the same weights the model was trained on
x = preprocess_input(inputs)
# set training to False to avoid keeping track of statistics in the batch norm layer
x = base_model(x, training=False)
# add the new Binary classification layers
# use global avg pooling to summarize the info in each channel
x = tfl.GlobalAveragePooling2D()(x)
# include dropout with probability of 0.2 to avoid overfitting
x = tfl.Dropout(0.2)(x)
# use a prediction layer with one neuron (as a binary classifier only needs one)
outputs = tfl.Dense(1)(x)
### END CODE HERE
model = tf.keras.Model(inputs, outputs)
return model
