Pad

public final class Pad

Pads a tensor.

This operation pads `input` according to the `paddings` and `constant_values` 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 padding values to add before the contents of `input` in that dimension, and `paddings[D, 1]` indicates how many padding values to add after the contents of `input` in that dimension. `constant_values` is a scalar tensor of the same type as `input` that indicates the value to use for padding `input`.

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]]
 # 'constant_values' is 0
 # 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]]

Inherited Methods

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static Pad<T> create (Scope scope, Operand<T> input, Operand<U> paddings, Operand<T> constantValues)

Factory method to create a class wrapping a new Pad operation.

Parameters
scope current scope
Returns
  • a new instance of Pad
