У меня есть вопрос по исправлению ошибки.
Я пытаюсь построить модель, которая объединяет структуру CNN и структуру GCN.
Я использовал dgl для модели GCN в среде pytorch.
Ввод модели состоит из изображения и графика. изображение размером 100 на 100 изображений.

Структура модели 

self.CNN = nn.Sequential(
                                nn.Conv2d(input_channel_1,output_channel_1,kernel_size_1,stride=stride_1),
                                nn.ReLU(),
                                nn.MaxPool2d(2),
                                nn.Conv2d(input_channel_2,output_channel_2,kernel_size_2,stride=stride_2),
                                nn.ReLU(),
                                nn.MaxPool2d(2),
                                nn.Conv2d(input_channel_3,output_channel_3,kernel_size_3,stride=stride_3),
                                nn.ReLU(),
                                nn.MaxPool2d(2),
                                nn.Flatten()
                                )

        # GCN layer for updating node embedding
        self.GCN = nn.ModuleList([
                                GraphConv(node_dimension_0, node_dimension_1),
                                GraphConv(node_dimension_1, node_dimension_2)
                                ])

        # classifier layer
        self.classifier = nn.Sequential(
                                nn.Linear(node_dimension_2,num_class)
                                )
