YOLOv7的neck部分可以通过替换激活函数来进行改变。在YOLOv5/YOLOv7的utils/activations.py文件中,可以添加想要替换的激活函数。以FReLU激活函数为例,可以复制粘贴以下代码:
```
# FReLU
class FReLU(nn.Module):
def __init__(self, c1, k=3): # ch_in, kernel
super().__init__()
self.conv = nn.Conv2d(c1, c1, k, 1, 1, groups=c1, bias=False)
self.bn = nn.BatchNorm2d(c1)
def forward(self, x):
return torch.max(x, self.bn(self.conv(x)))
```
通过添加这段代码,可以将YOLOv7的neck部分中的激活函数替换为FReLU激活函数。这样可以改变模型的特征提取方式,可能会对模型的性能产生影响。
