tf.keras.backend.repeat

TensorFlow 1 version View source on GitHub

Repeats a 2D tensor.

tf.keras.backend.repeat(
    x, n
)

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

Arguments:

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

Returns:

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)>
