tf.raw_ops.MirrorPadGrad

Gradient op for MirrorPad op. This op folds a mirror-padded tensor.

This operation folds the padded areas of input by MirrorPad according to the paddings you specify. paddings must be the same as paddings argument given to the corresponding MirrorPad op.

The folded size of each dimension D of the output is:

input.dim_size(D) - paddings(D, 0) - paddings(D, 1)

For example:

# 't' is [[1, 2, 3], [4, 5, 6], [7, 8, 9]].
# 'paddings' is [[0, 1]], [0, 1]].
# 'mode' is SYMMETRIC.
# rank of 't' is 2.
pad(t, paddings) ==> [[ 1,  5]
                      [11, 28]]

inputA Tensor. The input tensor to be folded.
paddingsA Tensor. Must be one of the following types: int32, int64. A two-column matrix specifying the padding sizes. The number of rows must be the same as the rank of input.
modeA string from: "REFLECT", "SYMMETRIC". The mode used in the MirrorPad op.
nameA name for the operation (optional).

A Tensor. Has the same type as input.
