mindspore.ops.argmin

mindspore.ops.argmin(input, axis=None, keepdims=False)[源代码]

返回tensor在指定轴上的最小值索引。

警告

从2.9.0(不含)之后版本开始,参数 axis 将重命名为 dimkeepdims 将重命名为 keepdim, 接口签名将变更为 mindspore.ops.argmin(input, dim=None, keepdim=False)

参数:
  • input (Tensor) - 输入tensor。

  • axis (Union[int, None],可选) - 指定轴。如果为 None ,计算 input 中的所有元素。默认 None

  • keepdims (bool,可选) - 输出tensor是否保留维度。默认 False

返回:

Tensor

支持平台:

Ascend GPU CPU

样例:

>>> import mindspore
>>> input = mindspore.tensor([[2, 5, 1, 6],
...                           [3, -7, -2, 4],
...                           [8, -4, 1, -3]])
>>> # case 1: By default, compute the minimum indices of all elements.
>>> mindspore.ops.argmin(input)
Tensor(shape=[], dtype=Int32, value= 5)
>>>
>>> # case 2: Compute the minimum indices along axis 1.
>>> mindspore.ops.argmin(input, axis=1)
Tensor(shape=[3], dtype=Int32, value= [2, 1, 1])
>>>
>>> # case 3: If keepdims=True, the output shape will be the same as that of the input.
>>> mindspore.ops.argmin(input, axis=1, keepdims=True)
Tensor(shape=[3, 1], dtype=Int32, value=
[[2],
 [1],
 [1]])
