TensorFlow Distribution is a powerful feature that allows you to distribute your TensorFlow computations across multiple machines. This tutorial will guide you through the basics of setting up and using TensorFlow Distribution.

Overview

  • What is TensorFlow Distribution? TensorFlow Distribution is a way to distribute TensorFlow computations across multiple machines or devices, allowing for more efficient and scalable machine learning models.

  • Why Use TensorFlow Distribution? Using TensorFlow Distribution, you can leverage the power of multiple GPUs or machines to speed up your training and inference processes.

Getting Started

Before you start, make sure you have TensorFlow installed. You can install TensorFlow using pip:

pip install tensorflow

Basic Concepts

  • Strategies TensorFlow Distribution uses strategies to control how computations are distributed. The most common strategies are:

    • tf.distribute.MirroredStrategy(): Synchronizes the variables across all replicas.
    • tf.distribute.MultiWorkerMirroredStrategy(): Synchronizes the variables across multiple workers.
    • tf.distribute.experimental.MultiWorkerMirroredStrategy(): Similar to MultiWorkerMirroredStrategy, but with more advanced features.
  • Replicas A replica is a copy of the model running on a different machine or device. The number of replicas depends on the strategy you choose.

Example

Here's a simple example of using tf.distribute.MirroredStrategy():

import tensorflow as tf

strategy = tf.distribute.MirroredStrategy()

with strategy.scope():
  model = tf.keras.models.Sequential([
    tf.keras.layers.Dense(10, activation='relu', input_shape=(32,)),
    tf.keras.layers.Dense(1)
  ])
  model.compile(optimizer='adam', loss='mean_squared_error')

# ... rest of the code
