No.262:
根据log日式显示，
改了argsort，就等于改了sort

auto rank = in_dims.size();这里rank指的是有几个维度，rank为0是0-dim。0-size指的是某个维度为0，进而所有维度的乘积也就是numel为0 请注意区分二者的区别。0-size Tensor的rank不一定为0，比如shape为[1,0,2]的Tensor，rank为3，numel = 1*0*2 = 0

@DanielSun11 可以review了

对于paddle.as_real的处理不够完善。
paddle.as_rea 报的是InvalidArgument，此时说明是参数检查报的错，但是并不代表不需要修改。请根据 https://www.paddlepaddle.org.cn/documentation/docs/zh/3.0-beta/api/paddle/as_real_cn.html#as-real 检查下参数是否合法，以及验证一下torch是否支持同样的shape。如果0 size Tensor的输入是合法的但是报了InvalidArgument，此时需要修改

没太明白，一切以APITest工具为准吗？可是错误是3月份的log,5月份的并没有as_real的错，而且直接调用，3月份的错误代码现在执行并不会报错

import paddle
x = paddle.to_tensor([10, 0, 10, 20], dtype = "complex128")
s = paddle.as_real(x)
print(s)

10, 0, 10, 20]

paddleAPITest的config中 paddle.as_real(Tensor([0, 10, 10, 20],"complex128"), ) ，[0, 10, 10, 20]是Tensor的shape，并不是tensor初始化的tuple，请重新测一下。测试结果以paddleAPITest为准，但是仍然需要添加单测来验证一些极端case。

好的，那我12重开PR

这个还需要改GPU、CPU的Kernel

enkilee · 2025-05-29T07:58:38Z

as_real按照3月份log的shape测试了下，好像也没有问题：

import paddle
x = paddle.randn(shape=[0, 4], dtype='complex64')
z = paddle.as_real(x)
print(z)

y = paddle.randn(shape=[10, 0, 10, 20], dtype='complex128')
z = paddle.as_real(y)
print(z)

result:

Tensor(shape=[0, 4, 2], dtype=float32, place=Place(gpu:0), stop_gradient=True,
       [])
Tensor(shape=[10, 0, 10, 20, 2], dtype=float64, place=Place(gpu:0), stop_gradient=True,
       [[],
