mindspore.ops.argmin
- mindspore.ops.argmin(input, axis=None, keepdims=False)[源代码]
返回tensor在指定维度上的最大值索引。
- 参数:
input (Tensor) - 输入tensor。
axis (Union[int, None],可选) - 指定计算维度。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

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 indice 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 same of that of the input. >>> mindspore.ops.argmin(input, axis=1, keepdims=True) Tensor(shape=[3, 1], dtype=Int32, value= [[2], [1], [1]])
