    tf.image.grayscale_to_rgb(
        images, name=None
    )

Outputs a tensor of the same `DType` and rank as `images`. The size of the
last dimension of the output is 3, containing the RGB value of the pixels.
The input images' last dimension must be size 1.

    original = tf.constant([[[1.0], [2.0], [3.0]]])
    converted = tf.image.grayscale_to_rgb(original)
    print(converted.numpy())
    [[[1. 1. 1.]
      [2. 2. 2.]
      [3. 3. 3.]]]
