That's because vgg19 doesn't have a fc member variable. Instead, it has a

 (classifier): Sequential (
 (0): Dropout (p = 0.5)
 (1): Linear (25088 -> 4096)
 (2): ReLU (inplace)
 (3): Dropout (p = 0.5)
 (4): Linear (4096 -> 4096)
 (5): ReLU (inplace)
 (6): Linear (4096 -> 100)
 )

To replace the last linear layer, a temporary solution would be

vgg19.classifier._modules['6'] = nn.Linear(4096, 8)

以上这篇Pytorch中的VGG实现修改最后一层FC就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
