The key points of the text cover building a simple CIFAR-10 image classifier using TensorFlow 2.0's Keras API, setting up a data pipeline with the dataset API, training the model with multiple GPUs and adding callbacks for monitoring progress and updating learning schedules. The tutorial demonstrates how to define a model using the Sequential API and functional API, set up a data pipeline, train the model, accelerate training speed with multiple GPUs, add callbacks for monitoring progress, updating learning schedules, and evaluate the model's performance.
