class mindspore.ops.InplaceAdd(*args, **kwargs)[source]

Adds v into specified rows of x. Computes y = x; y[i,] += v.

Parameters

indices (Union[int, tuple]) – Indices into the left-most dimension of x, and determines which rows of x to add with v. It is an integer or a tuple, whose value is in [0, the first dimension size of x).

Inputs:
• input_x (Tensor) - The first input is a tensor whose data type is float16, float32 or int32.

• input_v (Tensor) - The second input is a tensor that has the same dimension sizes as x except the first dimension, which must be the same as indices’s size. It has the same data type with input_x.

Outputs:

Tensor, has the same shape and dtype as input_x.

Raises
• TypeError – If indices is neither int nor tuple.

• TypeError – If indices is a tuple whose elements are not all int.

• ValueError – If length of shape of input_x is not equal to length of shape of input_v.

Examples

>>> indices = (0, 1)
>>> input_x = Tensor(np.array([[1, 2], [3, 4], [5, 6]]), mindspore.float32)
>>> input_v = Tensor(np.array([[0.5, 1.0], [1.0, 1.5]]), mindspore.float32)
