mindspore.Tensor.argmax_with_value
- Tensor.argmax_with_value(axis=0, keep_dims=False)[source]
Returns the maximum value with corresponding index.
Compute the max value of input Tensor on the specified axis, and return the max value and index.
Note
In auto_parallel and semi_auto_parallel mode, the first output index can not be used.
If there are multiple maximum values, the index of the first maximum value is used.
The value range of axis is [-dims, dims - 1]. dims is the dimension length of this tensor.
- Parameters
- Returns
tuple (Tensor), tuple of 2 tensors, containing the corresponding index and the maximum value of the input tensor.
index (Tensor) - The index for the maximum value of the input tensor. If keep_dims is
true
, the shape of output tensors is \((x_1, x_2, ..., x_{axis-1}, 1, x_{axis+1}, ..., x_N)\). Otherwise, the shape is \((x_1, x_2, ..., x_{axis-1}, x_{axis+1}, ..., x_N)\) .value (Tensor) - The maximum value of input tensor, with the same shape as index.

Examples
>>> import numpy as np >>> import mindspore >>> from mindspore import Tensor >>> x = Tensor(np.array([0.0, 0.4, 0.6, 0.7, 0.1]), mindspore.float32) >>> output, index = x.argmax_with_value() >>> print(output, index) 0.7 3 >>> output, index = x.argmax_with_value(keep_dims=True) >>> print(output, index) [0.7] [3]
