## [ torch 参数更多 ]torch.linalg.lu_factor | ||
|
||
### [torch.linalg.lu_factor](https://pytorch.org/docs/stable/generated/torch.linalg.lu_factor.html#torch.linalg.lu_factor) | ||
|
||
```python | ||
torch.linalg.lu_factor(A, *, bool pivot=True, out=None) | ||
``` | ||
|
||
### [paddle.linalg.lu](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api/paddle/linalg/lu_cn.html) | ||
|
||
```python | ||
paddle.linalg.lu(x, pivot=True, get_infos=False, name=None) | ||
``` | ||
|
||
Pytorch 相比 Paddle 支持更多其他参数,具体如下: | ||
|
||
### 参数映射 | ||
|
||
| PyTorch | PaddlePaddle | 备注 | | ||
| ------- | ------------ | ----------------------------------------------------- | | ||
| A | x | 表示需要进行 LU 分解的输入 Tensor ,仅参数名不一致。 | | ||
| pivot | pivot | 表示 LU 分解时是否进行旋转。 | | ||
| - | get_infos | 表示是否返回分解状态信息 , Paddle 保持默认即可。 | | ||
| out | - | 表示输出的 Tensor 元组 , Paddle 无此参数,需要转写。 | | ||
|
||
### 转写示例 | ||
|
||
#### out:指定输出 | ||
|
||
```python | ||
# Pytorch 写法 | ||
torch.linalg.lu_factor(A, out=(LU, pivots)) | ||
|
||
# Paddle 写法 | ||
y = paddle.linalg.lu(A) | ||
paddle.assign(y[0], out[0]), paddle.assign(y[1], out[1]) | ||
``` |

| pivot | pivot | 表示 LU 分解时是否进行旋转。 | | ||
| - | get_infos | 表示是否返回分解状态信息 ,PyTorch 返回 infos 信息,Paddle 需要设置为 True。 | | ||
| check_errors | - | 检查 infos 的内容,如果为非 0 抛出错误, Paddle 无此参数,一般对网络训练结果影响不大,可直接删除。 | | ||
| out | - | 表示输出的 Tensor 元组 ,Paddle 无此参数,需要转写。 | | ||
