Detailed Description

Adds extra values for specific axes.

Parameters

paddings	Vector of paddings in format [ pad_before, pad_after, // [0]th dimension pad_before, pad_after, // [1]st dimension ... pad_before, pad_after ] // [n]th dimension that represents number of padded values at every dimension starting from the first one. The rest of dimensions won't be padded.
value	Value to be padded. Defaults to zero.
type	Padding type: 'constant', 'reflect'
input_dims	Torch's parameter. If input_dims is not equal to the actual input dimensionality then the [0]th dimension is considered as a batch dimension and paddings are shifted to a one dimension. Defaults to -1 that means padding corresponding to paddings.
