    tensors,
    axis=-1
)

Arguments:

  • tensors: list of tensors to concatenate.
  • axis: concatenation axis.

Returns:

A tensor.

Example:

>>> a = tf.constant([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
>>> b = tf.constant([[10, 20, 30], [40, 50, 60], [70, 80, 90]])
>>> tf.keras.backend.concatenate((a, b), axis=-1)
