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)

以上這篇Pytorch中的VGG實現修改最後一層FC就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援我們。
