在ipython中寫了一個類，但是在實例化類的時候出現了  ‘module’ object has no attributes 'linear'的錯誤。import torch.nn as nnimport torch.nn.functional as Fclass Net(nn.Module):def __init__(self):nn.Module.__init__()#super(Net, self).__init__()self.conv2 = nn.Conv2d(6, 16, 5)self.fc1 = nn.Linear(16*5*5, 120)self.fc2 = nn.Linear(120, 84)self.fc3 = nn.linear(84, 10)def forward(self, x):x = F.max_pool2d(F.relu(self.conv1(x)), (2,2))x = F.max_pool2d(F.relu(self.conv2(x)), 2)x = x.view(x.size()[0], -1)x = F.relu(self.fc1(x))x = F.relu(self.fc2(x))x = self.fc3(x)return xnet = Net()print(net)
