pytorch中的fc和fc逆操作

將1*(1024*128)降維為(1*1024),將(1*1024)降維為(1*512)；

將(1*512)升維為(1*1024),將(1*1024)升維為1*(1024*128)；

        self.fc = nn.Sequential(
            nn.Linear(1024*128, 1024),
            nn.Linear(1024, 512)
        )
        self.upfc = nn.Sequential(
            nn.Linear(512, 1024),
            nn.Linear(1024, 1024*128),
        )

x6 = self.fc(x5)

x7 = self.upfc(x6)
