# tf.keras.backend.repeat

Repeats a 2D tensor.

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

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

A tensor.

#### Example:

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