# tf.repeat

Repeat elements of `input`

`input` An `N`-dimensional Tensor.
`repeats` An 1-D `int` Tensor. The number of repetitions for each element. repeats is broadcasted to fit the shape of the given axis. `len(repeats)` must equal `input.shape[axis]` if axis is not None.
`axis` An int. The axis along which to repeat values. By default (axis=None), use the flattened input array, and return a flat output array.
`name` A name for the operation.

A Tensor which has the same shape as `input`, except along the given axis. If axis is None then the output array is flattened to match the flattened input array.

#### Examples:

``````>>> repeat(['a', 'b', 'c'], repeats=[3, 0, 2], axis=0)
['a', 'a', 'a', 'c', 'c']
>>> repeat([[1, 2], [3, 4]], repeats=[2, 3], axis=0)
[[1, 2], [1, 2], [3, 4], [3, 4], [3, 4]]
>>> repeat([[1, 2], [3, 4]], repeats=[2, 3], axis=1)
[[1, 1, 2, 2, 2], [3, 3, 4, 4, 4]]
>>> repeat(3, repeats=4)
[3, 3, 3, 3]
>>> repeat([[1,2], [3,4]], repeats=2)
[1, 1, 2, 2, 3, 3, 4, 4]
