paddle. add ( x, y, name=None ) [source]

Elementwise Add Operator. Add two tensors element-wise The equation is:

\[Out=X+Y\]

$X$ the tensor of any dimension. $Y$ the tensor whose dimensions must be less than or equal to the dimensions of $X$.

This operator is used in the following cases:

The shape of $Y$ is the same with $X$.

The shape of $Y$ is a continuous subsequence of $X$.

For example:

               shape(X) = (2, 3, 4, 5), shape(Y) = (,)
shape(X) = (2, 3, 4, 5), shape(Y) = (5,)
shape(X) = (2, 3, 4, 5), shape(Y) = (4, 5), with axis=-1(default) or axis=2
shape(X) = (2, 3, 4, 5), shape(Y) = (3, 4), with axis=1
shape(X) = (2, 3, 4, 5), shape(Y) = (2), with axis=0
shape(X) = (2, 3, 4, 5), shape(Y) = (2, 1), with axis=0

              

Parameters

x (Tensor) – Tensor or LoDTensor of any dimensions. Its dtype should be int32, int64, float32, float64.
y (Tensor) – Tensor or LoDTensor of any dimensions. Its dtype should be int32, int64, float32, float64.
name (string, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

N-D Tensor. A location into which the result is stored. It’s dimension equals with x.

Examples

           >>> import paddle

>>> x = paddle.to_tensor([2, 3, 4], 'float64')
>>> y = paddle.to_tensor([1, 5, 2], 'float64')
>>> z = paddle.add(x, y)
>>> print(z)
Tensor(shape=[3], dtype=float64, place=Place(cpu), stop_gradient=True,
[3., 8., 6.])
