tf.keras.backend.spatial_3d_padding(
    x,
    padding=((1, 1), (1, 1), (1, 1)),
    data_format=None
)

Defined in tensorflow/python/keras/_impl/keras/backend.py.

Pads 5D tensor with zeros along the depth, height, width dimensions.

Pads these dimensions with respectively "padding[0]", "padding[1]" and "padding[2]" zeros left and right.

For 'channels_last' data_format, the 2nd, 3rd and 4th dimension will be padded. For 'channels_first' data_format, the 3rd, 4th and 5th dimension will be padded.

Arguments:

  • x: Tensor or variable.
  • padding: Tuple of 3 tuples, padding pattern.
  • data_format: One of channels_last or channels_first.

Returns:

A padded 5D tensor.

Raises:

  • ValueError: if data_format is neither channels_last or channels_first.
