tf.compat.v1.keras.backend.repeat, `tf.compat.v2.keras.backend.repeat`

tf.keras.backend.repeat(
    x, n
)

if x has shape (samples, dim) and n is 2, the output will have shape (samples, 2, dim).

Arguments
x	Tensor or variable.
n	Python integer, number of times to repeat.

Returns
A tensor.

Example:

b = tf.constant([[1, 2], [3, 4]])
b
<tf.Tensor: id=78, shape=(2, 2), dtype=int32, numpy=
array([[1, 2],
       [3, 4]], dtype=int32)>
tf.keras.backend.repeat(b, n=2)
<tf.Tensor: id=82, shape=(2, 2, 2), dtype=int32, numpy=
array([[[1, 2],
        [1, 2]],
       [[3, 4],
        [3, 4]]], dtype=int32)>
