mindspore.ops.median
- mindspore.ops.median(input, axis=- 1, keepdims=False)[源代码]
返回tensor在指定轴上的中位数及其索引。
警告
如果 input 的中值不唯一,则 indices 不一定对应第一个出现的中值。该接口的具体实现方式和后端类型相关,CPU和GPU的返回值可能不相同。
- 参数:
input (Tensor) - 输入tensor。
axis (int,可选) - 指定计算的轴。默认
-1
。keepdims (bool,可选) - 输出tensor是否保留维度。默认
False
。
- 返回:
两个tensor组成的tuple(median, median_indices)
- 支持平台:
GPU
CPU
样例:
>>> import mindspore >>> input = mindspore.tensor([[9, 3, 4, 5], ... [5, 2, 7, 4], ... [8, 1, 3, 6]]) >>> # case 1: By default, compute the median along axis -1. >>> mindspore.ops.median(input) (Tensor(shape=[3], dtype=Int64, value= [4, 4, 3]), Tensor(shape=[3], dtype=Int64, value= [2, 3, 2])) >>> >>> # case 2: Compute the median along axis 0. >>> mindspore.ops.median(input, axis=0) (Tensor(shape=[4], dtype=Int64, value= [8, 2, 4, 5]), Tensor(shape=[4], dtype=Int64, value= [2, 1, 0, 0])) >>> >>> # case 3: If keepdims=True, the output shape will be same of that of the input. >>> mindspore.ops.median(input, axis=0, keepdims=True) (Tensor(shape=[1, 4], dtype=Int64, value= [[8, 2, 4, 5]]), Tensor(shape=[1, 4], dtype=Int64, value= [[2, 1, 0, 0]]))
