class mindspore.ops.Argmax(axis=- 1, output_type=mstype.int32)[source]

Returns the indices of the maximum value along a specified axis of a Tensor.

Refer to mindspore.ops.argmax() for more details.

Parameters

  • axis (int) – Axis where the Argmax operation applies to. Default: -1 .

  • output_type (mindspore.dtype) – Output data type. Supported types: mstype.int32 , mstype.int64 . Default: mstype.int32 .

Inputs:

  • input_x (Tensor) - The input tensor. \((N, *)\) where \(*\) means, any number of additional dimensions.

Outputs:

Tensor, indices of the max value of input tensor across the axis.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> input_x = Tensor(np.array([[1, 20, 5], [67, 8, 9], [130, 24, 15]]).astype(np.float32))
>>> output = ops.Argmax(output_type=mindspore.int32)(input_x)
>>> print(output)
