See also tf.ones.

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.Tensor: shape=(2, 3), dtype=int32, numpy= 
  array([[1, 1, 1], 
         [1, 1, 1]], dtype=int32)> 


  • 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).


A Tensor with all elements set to one.
