.. py:class:: ExactPadding2d(kernel, stride=1, dilation=1, mode='same')

   Bases: :py:obj:`torch.nn.Module`


   This function calculate exact padding values for 4D tensor inputs,
   and support the same padding mode as tensorflow.

   :param kernel: kernel size.
   :type kernel: int or tuple
   :param stride: stride size.
   :type stride: int or tuple
   :param dilation: dilation size, default with 1.
   :type dilation: int or tuple
   :param mode: padding mode can be ('same', 'symmetric', 'replicate', 'circular')
   :type mode: srt
