Question

我加载了'state_dict'的resnet50.pth和KeyError pytorch版本是0.4.1

我尝试删除/添加torch.nn.parallel，但没有帮助和pytorch API中加载的resnet50.pth

相关代码

model = ResNet(len(CLASSES), pretrained=args.use_imagenet_weights)
if cuda_is_available:
    model = nn.DataParallel(model,  device_ids=[2]).cuda()
if args.model:
    print("Loading model " + args.model)
    state_dict = torch.load(args.model)['state_dict']
    model.load_state_dict(state_dict)

追踪

Loading model resnet50-19c8e357.pth
Traceback (most recent call last):
  File "train.py", line 67, in <module>
    state_dict = torch.load(args.model)['state_dict']
KeyError: 'state_dict'

当print（torch.load（args.model）.keys（））

只想运行plz

Answer 1

您可能是说以下意思吗？

equals

根据您的编辑，看来您的模型就是模型本身。没有state_dict。因此，只需使用

state_dict = torch.load(args.model['state_dict'])

Answer 2

您可以输出已加载模型的密钥吗？

print(torch.load(args.model).keys())

当我用pytorch加载resnet50.pth的state_dict时怎么办
