The strategy essentially copies all of In this article, we will discuss distributed training with Tensorflow and understand how you can incorporate it into your AI workflows. fit or a custom training loop), distributed training in TensorFlow 2 involves a 'cluster' with several 'jobs', and each of the jobs may have one or more 'tasks'. The code here is similar to the multi-GPU training tutorial with one key difference: when using Estimator for multi-worker training, it is necessary to shard the dataset by the number of workers to ensure model convergence. For example, the tutorial code exports the QCNN readout tensor as a histogram. 6. , which is one of the major features in TensorFlow 2. It allows you to carry out distributed training using existing models and training code with minimal changes. Many of the examples focus We’ll explain how TensorFlow distributed training works and show brief tutorials to get you oriented.
