WebMay 14, 2024 · Hi, I have defined the following 2 architectures using some valuable suggestions in this forum. In my opinion they are the same, but I am getting very different performance after the same number of epochs. The only difference is that one of them uses nn.Sequential and the other doesn’t. Any ideas? The first architecture is the following: … Webdef size_after_relu(self, x): x = self.maxpool(F.relu(self.conv1(x.float()))) x = self.maxpool(F.relu(self.conv2(x.float()))) return x.size() # after obtaining the size in …
