mindspore.ops.tensor_scatter_max

mindspore.ops.tensor_scatter_max(input_x, indices, updates)[source]

mindspore.ops.tensor_scatter_max is deprecated from version 2.9.0 and will be removed in a future version.

Return a new tensor by performing a maximum update on input_x at the specified indices with the given update values.

\[output\left [indices \right ] = \max(input\_x, updates)\]

Note

On GPU, if some values of the indices are out of bounds, instead of raising an index error, the corresponding updates will not be updated to self tensor.
On CPU, if some values of the indices are out of bounds, raising an index error.
On Ascend, out of bounds checking is not supported. If some values of the indices are out of bounds, unknown errors may be caused.

Parameters:

input_x (Tensor) – The input tensor.
indices (Tensor) – The specified indices. The rank must be at least 2.
updates (Tensor) – The update values.

Returns:

Tensor

Supported Platforms:: Deprecated

Examples

>>> import mindspore
>>> input_x = mindspore.tensor([[1, 2, 3], [4, 5, 6]])
>>> indices = mindspore.tensor([[0, 0], [1, 1]])
>>> updates = mindspore.tensor([5, 5])
>>> mindspore.ops.tensor_scatter_max(input_x, indices, updates)
Tensor(shape=[2, 3], dtype=Int64, value=
[[5, 2, 3],
 [4, 5, 6]])
