experimental_distribute_dataset( dataset ) Distributes a tf.data.Dataset instance provided via dataset . The returned distributed dataset can be iterated over similar to how regular datasets can.
12/15/2020 · When using tf.distribute.Strategy.experimental_distribute_dataset APIs with a multiple worker setup, users pass a tf.data.Dataset that reads from files. If the tf.data.experimental.AutoShardPolicy is set to AUTO or FILE, the actual per step batch size may be smaller than the user defined global batch size. This can happen when the remaining elements in the.

Use tf.distribute.Strategy.experimental_distribute_dataset to convert a tf.data.Dataset to something that produces per-replica values. If you want to manually specify how the dataset should be partitioned across replicas, use tf.distribute.Strategy.experimental_distribute_datasets_from_function instead.
`tf.distribute.experimental_distribute_dataset` or `tf.distribute. experimental_distribute_datasets_from_function `. Any stateful `tf.distribute. distribute_datasets_from_function `. Any stateful: ops that the dataset may have are currently ignored. For example, if your: dataset has a `map_fn` that uses `tf.random.uniform` to rotate an image,, You can use this API to create a dataset before calling tf.distribute.Strategy.experimental_distribute_dataset. Another way of iterating over your data is to explicitly use iterators. You may want to do this when you want to run for a given number of steps as opposed to iterating over the entire dataset.
12/14/2020 · tf.data.experimental.DistributeOptions () You can set the distribution options of a dataset through the experimental_distribute property of tf.data.Options; the property is an instance of tf.data.experimental.DistributeOptions.
In the tensorflow tutorial for distributed training (https://www.tensorflow.org/guide/distributed_training), the tf.datadatagenerator is converted into a distributed dataset as follows: dist_dataset = mirrored_strategy.experimental_distribute_dataset(dataset), 1/8/2020 · Custom training loop support on TPUs and TPU pods is avaiable through strategy.experimental_ distribute_dataset , strategy.experimental_distribute_datasets_from_function, strategy.experimental_run_v2, strategy.reduce. Support for a global distribution strategy through tf.distribute.experimental_set_strategy(), in addition to strategy.scope …
Keras fit does not do much magic other than using strategy.experimental_ distribute_dataset and strategy.run like you used. Are you using the exact same dataset as in the code above for training? (and the forward pass of the model is the same as the model.inference used above?–
