01.03.2019 · Introduction. The Keras functional API is a way to create models that are more flexible than the tf.keras.Sequential API. The functional API can handle models with non-linear topology, shared layers, and even multiple inputs or outputs. The main idea is that a deep learning model is usually a directed acyclic graph (DAG) of layers.

In this step-by-step Keras tutorial, you’ll learn how to build a convolutional neural network in Python! In fact, we’ll be training a classifier for handwritten digits that boasts over 99% accuracy on the famous MNIST dataset. Before we begin, we should note that this guide is geared toward beginners who are interested in applied deep learning.

09.12.2021 · For example, I have a project that needs Python 3.5 using OpenCV 3.3 with older Keras-Theano backend but in the other project I have to use Keras with the latest version and a Tensorflow as it backend with Python 3.6.6 support

Here's a low-level training loop example, combining Keras functionality with the TensorFlow GradientTape : import tensorflow as tf # Prepare an optimizer.
