return tf.data.Dataset object

shard(num_shards, index)

creates a Dataset that includes only 1/num_shards of this dataset

batch_wise_shuffle(batch_size=1, epoch=-1, seed=917)

Batch-wise shuffling of the data entries.

Parameters
  • batch_size (int, optional) – an integer for the batch size. Defaults to 1

  • . (in batch_bins mode) –
