@mratsim & @diegslva, when I want to save the trained (i.e., fine tuned) models of ResNet and DenseNet the torch.save(MyModel.state_dict(), './model.pth') method doesn’t work correctly; and when I used the torch.save(MyModel, './model.pth') then the models are saved correctly. It means that when I load my saved models via the first approach, my models don’t give me correct results, however when I use the second approach the results are good. Am I correct? would you please explain why this issue occurred?
