dropout2d
-------------------------------

.. py:function:: paddle.nn.functional.dropout2d(x, p=0.5, training=True, name=None)
.. py:function:: paddle.nn.functional.dropout2d(x, p=0.5, training=True, data_format='NCHW', name=None)

根据丢弃概率 `p`,在训练过程中随机将某些通道特征图置 0 (对一个形状为 `NCHW` 的 4 维 Tensor,通道特征图指的是其中的形状为 `HW` 的 2 维特征图)。

想问一下,该目录会在官网公开暴露吗? model_convert/convert_from_pytorch/api_difference/functional/...

因为在官网路径上没找到

@zhwesky2010 可以看下么,我理解应该是不会在官网公布的吧

## [ torch 参数更多 ]torch.nn.functional.dropout2d

### [torch.nn.functional.dropout2d](https://pytorch.org/docs/stable/generated/torch.nn.functional.dropout2d.html#torch.nn.functional.dropout2d)

```python
torch.nn.functional.dropout2d(input, p=0.5, training=True, inplace=False)
```

### [paddle.nn.functional.dropout2d](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api/paddle/nn/functional/dropout2d_cn.html)

```python
paddle.nn.functional.dropout2d(x, p=0.5, training=True, data_format='NCHW', name=None)
```

PyTorch 对于 dropout1d/dropout2d/dropout3d,是将某个 Channel 以一定概率全部置 0,Paddle 是所有元素以一定概率置 0,但该差异一般不影响网络训练效果。
其中 PyTorch 相比 Paddle 支持更多其他参数,具体如下:
### 参数映射
| PyTorch | PaddlePaddle | 备注 |
| -------- | ------------ | --------------------------------------------------------------------------------------------------------------- |
| input | x | 输入的多维 Tensor,仅参数名不一致。 |
| p | p | 将输入节点置 0 的概率,即丢弃概率。 |
| training | training | 标记是否为训练阶段。 |
| inplace | - | 表示在不更改变量的内存地址的情况下,直接修改变量的值,Paddle 无此参数,一般对网络训练结果影响不大,可直接删除。 |
| - | data_format | 指定输入的数据格式,PyTorch 无此参数,Paddle 保持默认即可。 |
