Creates a tensor with all elements set to 1.

    tensor, dtype=None, name=None, optimize=True

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 specify a new type (dtype) for the returned tensor.

For example:

tensor = tf.constant([[1, 2, 3], [4, 5, 6]])
tf.ones_like(tensor)  # [[1, 1, 1], [1, 1, 1]]


  • tensor: A Tensor.
  • dtype: A type for the returned Tensor. Must be float32, float64, int8, uint8, int16, uint16, int32, int64, complex64, complex128 or bool.
  • name: A name for the operation (optional).
  • optimize: if true, attempt to statically determine the shape of 'tensor' and encode it as a constant.
