torch.median
torch.median(input, dim=-1, keepdim=False, *, out=None) -> Tensor

Differences
PyTorch: Output the median and index of input
according to the specified dim
. keepdim
controls whether the output and input have the same dimension. Return the median of all elements when the input has only input
, or the median and index of the specified dimension when the input contains dim
. out
can get the output.
MindSpore: Output the median and index of input
according to the specified axis
. The keepdims
function is identical to PyTorch. Unlike Pytorch, MindSpore returns the median and index in the specified dimension, regardless of whether the input contains axis
or not. MindSpore does not have out
parameter.

Code Example
# PyTorch

print(torch.median(input))
# tensor(2.)
print(torch.median(input, dim=1, keepdim=True))
# torch.return_types.median(
# values=tensor([[1.],
# [2.]]),
# indices=tensor([[3],
# [2]]))
# MindSpore
import mindspore
x = mindspore.Tensor([[1, 2.5, 3, 1], [2.5, 3, 2, 1]], dtype=mindspore.float32)
print(mindspore.ops.median(x, axis=1, keepdims=True))
# (Tensor(shape=[2, 1], dtype=Float32, value=
