WebMar 11, 2024 · 对于这个问题，我可以回答。您可以使用PyTorch提供的state_dict()方法来获取模型的参数，然后修改这些参数。修改后，您可以使用load_state_dict()方法将修改后的参数加载回模型中，并使用torch.save()方法将模型保存到磁盘上。 WebMay 17, 2024 · A single optimizer/scheduler group can be configured to accept settings for one class or multiple classes using class_path and init_args to follow the same pattern that LightningCLI already uses. There would be a function to ease instantiation. This is particularly important when a class is defined using class_path and init_args.
