Repeats the elements of a tensor along an axis, like np.repeat
.
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: shape=(6,), dtype=int32,
numpy=array([1, 1, 2, 2, 3, 3], dtype=int32)>
