## [ 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.window._blackman]()

```python
paddle.audio.functional.window._blackman(M: int, sym: bool = True, dtype: str = '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_length | M | 输入窗口的长度。 |
| periodic | sym | 判断是否返回适用于过滤器设计的对称窗口,功能相反,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

#### 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=True)

# Paddle 写法
paddle.audio.functional.window._blackman(5, sym=False)
```

#### 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.window._blackman(5)
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.window._blackman(5)
y.cpu()
