Я могу получить сводную информацию о модели из pytorch, как и керасы:
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
resnet = models.resnet18().to(device)
summary(resnet , (3, 224, 224))
результат выглядит так:

Как получить узлы-предшественники каждого слоя в pytorch?Я посмотрел на OrderDict, в котором нет информации об узлах-предшественниках.Как я могу получить информацию о каждом слое узлов-предшественников в pytorch?
