Given a single tensor (tensor), this operation returns a tensor of the same type and shape as tensor with all elements set to 1. Optionally, you can use dtype to specify a new type for the returned tensor.

For example:

tensor = tf.constant([[1, 2, 3], [4, 5, 6]]) tf.ones_like(tensor) <tf.Tensor: shape=(2, 3), dtype=int32, numpy= array([[1, 1, 1], [1, 1, 1]], dtype=int32)>

Note that the layout of the input tensor is not preserved if the op is used inside tf.function. To obtain a tensor with the same layout as the input, chain the returned value to a dtensor.relayout_like.

Args
input A Tensor.
dtype A type for the returned Tensor. Must be float16, float32,float64, int8, uint8, int16, uint16, int32, int64,complex64, complex128, bool or string.
name A name for the operation (optional).
layout Optional, tf.experimental.dtensor.Layout. If provided, the result is a DTensor with the provided layout.
Returns
A Tensor with all elements set to one.
