Machine Learning with TensorFlow 1.x

By: Quan Hua, Saif Ahmed, Shams Ul Azeem

Overview of this book

Google's TensorFlow is a game changer in the world of machine learning. It has made machine learning faster, simpler, and more accessible than ever before. This book will teach you how to easily get started with machine learning using the power of Python and TensorFlow 1.x. Firstly, you’ll cover the basic installation procedure and explore the capabilities of TensorFlow 1.x. This is followed by training and running the first classifier, and coverage of the unique features of the library including data ?ow graphs, training, and the visualization of performance with TensorBoard—all within an example-rich context using problems from multiple industries. You’ll be able to further explore text and image analysis, and be introduced to CNN models and their setup in TensorFlow 1.x. Next, you’ll implement a complete real-life production system from training to serving a deep learning model. As you advance you’ll learn about Amazon Web Services (AWS) and create a deep neural network to solve a video action recognition problem. Lastly, you’ll convert the Caffe model to TensorFlow and be introduced to the high-level TensorFlow library, TensorFlow-Slim. By the end of this book, you will be geared up to take on any challenges of implementing TensorFlow 1.x in your machine learning environment.

Installing TensorBoard

TensorFlow comes prepackaged with TensorBoard, so it will already be installed. It runs as a locally served web application accessible via the browser at http://0.0.0.0:6006. Conveniently, there is no server-side code or configurations required.

Depending on where your paths are, you may be able to run it directly, as follows:

tensorboard --logdir=/tmp/tensorlogs

If your paths are not correct, you may need to prefix the application accordingly, as shown in the following command line:

tf_install_dir/ tensorflow/tensorboard --
logdir=/tmp/tensorlogs

On Linux, you can run it in the background and just let it keep running, as follows:

nohup tensorboard --logdir=/tmp/tensorlogs &

Some thought should be put into the directory structure though. The Runs list on the left side of the dashboard is driven by subdirectories in the logdir location. The following image...
