tf.compat.v1.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)>
