This interface is used to construct a callable object of the ``Pad2D`` class.
The Pad2D layer pads the input tensor boundaries according to 'paddings' and 'mode'.
If mode is 'reflect', paddings[0] and paddings[1] must be no greater
than height-1. And the width dimension has the same condition.
Parameters:
paddings (int | List[int32]): The padding size. If padding is a int, uses the same
padding in all boundaries, if padding is a List, it must contain four integers,
(padding_top, padding_bottom, padding_left, padding_right).
Default is [0, 0, 0, 0].
mode (str): Three modes: 'constant' (default), 'reflect', 'edge' .
When in 'constant' mode, this op uses a constant value to pad the input tensor.
When in 'reflect' mode, uses reflection of the input boundaries to pad the input tensor.
When in 'edge' mode, uses input boundaries to pad the input tensor.
Default is 'constant'
pad_value (float32): The value to fill the padded areas in 'constant' mode . Default is 0.0
data_format (str): An string from: "NHWC", "NCHW". Specify the data format of
the input data.
Default is "NCHW"

This interface is used to construct a callable object of the ``ConstantPad2d`` class.
Uses a constant value to pad the input tensor.
This interface is used to construct a callable object of the ``Pad2D`` class.
Pad tensor according to 'pad', 'mode' and 'value'.
If mode is 'reflect', pad[0] and pad[1] must be no greater
than width-1. The height dimension has the same condition.
Parameters:
padding (Tensor | List[int32]): The padding size with data type int32. [len(padding)/2] dimensions
of input will be padded. The pad has the form (pad_left, pad_right, pad_top, pad_bottom).
mode (str): Four modes: 'constant' (default), 'reflect', 'replicate', 'circular'.
When in 'constant' mode, this op uses a constant value to pad the input tensor.
When in 'reflect' mode, uses reflection of the input boundaries to pad the input tensor.
When in 'replicate' mode, uses input boundaries to pad the input tensor.
When in 'circular' mode, uses circular input to pad the input tensor.
Default is 'constant'.
value (float32): The value to fill the padded areas. Default is 0.0
data_format (str): An string from: "NCHW", "NHWC". Specify the data format of the input data.
Default is "NCHW"
name (str, optional) : The default value is None. Normally there is no need for
user to set this property. For more information, please refer to :ref:`api_guide_Name`.
Returns:
None
