Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Use opencv-python to read the RGB image located at image_file_path.”

A block of code is set as follows:

def build_fe_model():
    """"Create feature extraction model from the pre-trained model ResNet50V2"""
    # create the pre-trained part of the network, excluding FC layers
    base_model = tf.keras.applications.MobileNetV3Small(

Any command-line input or output is written as follows:

import tensorflow.keras

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

import io
image = Image.open(io.BytesIO(response.content)) 
image.show()
