## [ torch 参数更多 ] torch.blackman_window | ||
|
||
### [torch.blackman_window](https://pytorch.org/docs/stable/generated/torch.blackman_window.html) | ||
|
||
```python | ||
torch.blackman_window(window_length, periodic=True, *, dtype=None, layout=torch.strided, device=None, requires_grad=False) | ||
``` | ||
|
||
### [paddle.audio.functional.get_window](https://www.paddlepaddle.org.cn/documentation/docs/zh/2.6/api/paddle/audio/functional/get_window_cn.html#get-window) | ||
|
||
```python | ||
paddle.audio.functional.get_window(window, win_length, fftbins=True, dtype='float64') | ||
``` | ||
|
||
PyTorch 相比 Paddle 支持更多其他参数,具体如下: | ||
### 参数映射 | ||
|
||
| PyTorch | PaddlePaddle | 备注 | | ||
| ------------- | ------------ | ------------------------------------------------------ | | ||
| - | window | 窗函数类型,Pytorch 无此参数,Paddle 需设置为 `blackman`。 | | ||
| window_length | win_length | 输入窗口的长度,仅参数名不同。 | | ||
| periodic | fftbins | 判断是否返回适用于过滤器设计的对称窗口,功能相反,Pytorch 默认值为 True 时,Paddle 须设置为 False,需要转写。 | | ||
| dtype | dtype | 返回 Tensor 的数据类型。 | | ||
| layout | -| 表示布局方式, Paddle 无此参数,一般对网络训练结果影响不大,可直接删除。 | | ||
| device | - | 表示 Tensor 存放设备位置,Paddle 无此参数,需要转写。 | | ||
| requires_grad | - | 表示是否计算梯度, Paddle 无此参数,需要转写。 | | ||
|
||
### 转写示例 | ||
|
||
#### window:窗函数类型 | ||
```python | ||
# PyTorch 写法 | ||
torch.blackman_window(5) | ||
|
||
# Paddle 写法 | ||
paddle.audio.functional.get_window('blackman', 5, fftbins = False) | ||
``` | ||
|
||
#### periodic:判断是否返回适用于过滤器设计的对称窗口 | ||
```python | ||
# PyTorch 写法 | ||
torch.blackman_window(5, periodic = False) | ||
|
||
# Paddle 写法 | ||
paddle.audio.functional.get_window('blackman', 5, fftbins = True) | ||
``` | ||
|
||
#### requires_grad:是否需要求反向梯度,需要修改该 Tensor 的 stop_gradient 属性 | ||
```python | ||
# PyTorch 写法 | ||
torch.blackman_window(5, requires_grad = True) | ||
|
||
# Paddle 写法 | ||
x = paddle.audio.functional.get_window('blackman', 5, fftbins = False) | ||
x.stop_gradient = False | ||
``` | ||
|
||
#### device: Tensor 的设备 | ||
```python | ||
# PyTorch 写法 | ||
torch.blackman_window(5, device = torch.device('cpu')) | ||
|
||
# Paddle 写法 | ||
y = paddle.audio.functional.get_window('blackman', 5, fftbins = False) | ||
y.cpu() | ||
