RuntimeError: Error(s) in loading state_dict for Net: Missing key(s) in state_dict: "fc1.weight", "

在载入模型参数前加上：

model = nn.DataParallel(model) 

还有错误如：IncompatibleKeys(missing_keys=[], unexpected_keys=[])

或者错误：RuntimeError: module must have its parameters and buffers on device cuda:0 (device_ids[0])

再加上：

model = nn.DataParallel(model,device_ids=[0,1]) 
device = torch.device("cuda:0" ) 
model.to(device)
