Distributed Training With TensorFlow TensorFlow Core

1. tf.distribute.Strategyis a TensorFlow API to distribute training across multiple GPUs, multiple machines, or TPUs. Using this API, you can distribute your existing models and training code with minimal code changes. tf.distribute.Strategyhas been designed with these key goals in mind: 1. Easy to use and support multiple user segments, including researchers, machine learning engineers, etc. 2. Provide good performance out of the box. 3. Easy switching between strategies. You can distribute training using tf.distribute.Strategy with a high-level API like Keras Model.fit, as well as custom training loops(and, in general, any computation using TensorFlow). In TensorFlow 2.x, you can execute your programs eagerly, or in a graph using tf.function. tf.distribute.Strategy intends to support both these modes of execution, but works best with tf.function. Eager mode is only recommended for debugging purposes and not supported for tf.distribute.TPUStrategy. Although training is the focus of th
2. tf.distribute.Strategyintends to cover a number of use cases along different axes. Some of these combinations are currently supported and others will be added in the future. Some of these axes are: 1. Synchronous vs asynchronous training:These are two common ways of distributing training with data parallelism. In sync training, all workers train over different slices of input data in sync, and aggregating gradients at each step. In async training, all workers are independently training over the input data and updating variables asynchronously. Typically sync training is supported via all-reduce and async through parameter server architecture. 2. Hardware platform:You may want to scale your training onto multiple GPUs on one machine, or multiple machines in a network (with 0 or more GPUs each), or on Cloud TPUs. In order to support these use cases, TensorFlow has MirroredStrategy, TPUStrategy, MultiWorkerMirroredStrategy, ParameterServerStrategy, CentralStorageStrategy, as well as ot

Distributed Input TensorFlow Core

1. To use tf.distribute APIs to scale, it is recommended that users use tf.data.Dataset to represent their input. tf.distribute has been made to work efficiently with tf.data.Dataset (for example, automatic prefetch of data onto each accelerator device) with performance optimizations being regularly incorporated into the implementation. If you have a use case for using something other than tf.data.Dataset, please refer a later section in this guide.In a non distributed training loop, users first create a tf.data.Datasetinstance and then iterate over the elements. For example: To allow users to use tf.distribute strategy with minimal changes to a user’s existing code, two APIs were introduced which would distribute a tf.data.Dataset instance and return a distributed dataset object. A user could then iterate over this distributed dataset instance and train their model as before. Let us now look at the two APIs - tf.distribute.Strategy.experimental_distribute_dataset and tf.distribute.Str

Custom Training With Tf.distribute.Strategy TensorFlow Core

If you are using regularization losses in your model then you need to scale the loss value by number of replicas. You can do this by using the tf.nn.scale_regularization_loss function. Using tf.reduce_mean is not recommended. Doing so divides the loss by actual per replica batch size which may vary step to step.
