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

tf.keras.backend.repeat_elements(
    x, rep, axis
)

If x has shape (s1, s2, s3) and axis is 1, the output will have shape (s1, s2 * rep, s3).

Arguments
x	Tensor or variable.
rep	Python integer, number of times to repeat.
axis	Axis along which to repeat.

Returns
A tensor.

Example:

b = tf.constant([1, 2, 3])
tf.keras.backend.repeat_elements(b, rep=2, axis=0)
<tf.Tensor: id=70, shape=(6,), dtype=int32,
    numpy=array([1, 1, 2, 2, 3, 3], dtype=int32)>
