tf.data.experimental.Counter

Creates a Dataset that counts from start in steps of size step.

Used in the notebooks

Used in the guide Used in the tutorials

Unlike tf.data.Dataset.range which will stop at some ending number, Counter will produce elements indefinitely.

start (Optional.) The starting value for the counter. Defaults to 0.
step (Optional.) The step size for the counter. Defaults to 1.
dtype (Optional.) The data type for counter elements. Defaults to tf.int64.

A Dataset of scalar dtype elements.
