你可以在 `__init__` 方法中添加以下代码:
```
print("in_channels:", in_channels)
print("reduction:", reduction)
```
在 `forward` 方法中添加以下代码:
```
print("x.shape:", x.shape)
```
这样就可以在打印的信息中看到传入的参数和输入的张量形状了。完整的代码如下:
```
class SelfAttention(nn.Module):
def __init__(self, in_channels, reduction=4):
super(SelfAttention, self).__init__()
self.avg_pool = nn.AdaptiveAvgPool1d(1) #
print("in_channels:", in_channels)
print("reduction:", reduction)
self.fc1 = nn.Conv1d(in_channels, in_channels // reduction, 1, bias=False)
self.relu = nn.ReLU(inplace=True)
self.fc2 = nn.Conv1d(in_channels // reduction, in_channels, 1, bias=False)
self.sigmoid = nn.Sigmoid()
def forward(self, x):
print("x.shape:", x.shape)
b, c, n = x.size()
y = self.avg_pool(x)
print("y.shape=", y.shape) #
y = self.fc1(y)
y = self.relu(y)
y = self.fc2(y)
y = self.sigmoid(y)
return x * y.expand_as(x)
```
