Pads a tensor with zeros.
tf.raw_ops.Pad(
    input, paddings, name=None
)
This operation pads a input with zeros according to the paddings you
specify. paddings is an integer tensor with shape [Dn, 2], where n is the
rank of input. For each dimension D of input, paddings[D, 0] indicates
how many zeros to add before the contents of input in that dimension, and
paddings[D, 1] indicates how many zeros to add after the contents of input
in that dimension.
The padded size of each dimension D of the output is:
paddings(D, 0) + input.dim_size(D) + paddings(D, 1)
For example:
# 't' is [[1, 1], [2, 2]]
# 'paddings' is [[1, 1], [2, 2]]
# rank of 't' is 2
pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]
                      [0, 0, 1, 1, 0, 0]
                      [0, 0, 2, 2, 0, 0]
                      [0, 0, 0, 0, 0, 0]]
