问题描述：
这是我的代码，本体为一个pytorch模型，希望通过查看父类继承确定是否为网络模型。
class Net(nn.Module):
def __init__(self):
super(Net, self).__init__()
self.conv1 = nn.Conv2d(1, 32, 3, 1)
self.conv2 = nn.Conv2d(32, 64, 3, 1)
self.dropout1 = nn.Dropout2d(0.25)
self.dropout2 = nn.Dropout2d(0.5)
self.fc1 = nn.Linear(9216, 128)
self.fc2 = nn.Linear(128, 10)
def forward(self, x):
x = self.conv1(x)
x = F.relu(x)
x = self.conv2(x)
x = F.relu(x)
x = F.max_pool2d(x, 2)
x = self.dropout1(x)
x = torch.flatten(x, 1)
x = self.fc1(x)
x = F.relu(x)
x = self.dropout2(x)
x = self.fc2(x)
output = F.log_softmax(x, dim=1)
return output
net = Net()
print(net.__bases__)
结果报错：该类没有__bases__属性（？这个属性不是每个类都有的吗？当时头顶两个问号）
Traceback (most recent call last):
File "C:/Users/Ming/Desktop/user_project/Test2.py", line 7, in <module>
print(net.__bases__)
File "D:\Anaconda3\lib\site-packages\torch\nn\modules\module.py", line 1131, in __getattr__
type(self).__name__, name))
AttributeError: 'Net' object has no attribute '__bases__'
后来仔细研究发现了，取__bases__属性，首先要唤出该类定义，也就是需要添加__class__，具体如下：
net = Net()
print(net.__class__.__bases__)
得出结果：
(<class 'torch.nn.modules.module.Module'>,)
