tf.data.experimental.enumerate_dataset

A transformation that enumerates the elements of a dataset. (deprecated)

tf.data.experimental.enumerate_dataset( start=0 )

It is similar to python's enumerate. For example:

# NOTE: The following examples use `{ ... }` to represent the # contents of a dataset. a = { 1, 2, 3 } b = { (7, 8), (9, 10) } # The nested structure of the `datasets` argument determines the # structure of elements in the resulting dataset. a.apply(tf.data.experimental.enumerate_dataset(start=5)) => { (5, 1), (6, 2), (7, 3) } b.apply(tf.data.experimental.enumerate_dataset()) => { (0, (7, 8)), (1, (9, 10)) }

start A tf.int64 scalar tf.Tensor, representing the start value for enumeration.

A Dataset transformation function, which can be passed to tf.data.Dataset.apply.
