这个错误通常是由于在保存模型状态时出现问题导致的。在您的代码中,您使用了 `torch.save(model.state_dict,"LSTMmodel1.pth")` 来保存模型的状态字典,但是这里的 `state_dict` 后面应该是一个方法而不是一个函数。
要解决这个问题,您需要将 `torch.save()` 函数中的 `model.state_dict` 改为 `model.state_dict()`,以调用该方法并获取模型的状态字典。正确的代码应该是:
```python
torch.save(model.state_dict(), "LSTMmodel1.pth")
```
请注意括号的位置,确保调用了 `state_dict()` 方法并将其结果传递给 `torch.save()` 函数。这样可以确保正确地保存了模型的状态字典。
请尝试修改您的代码并再次运行,看看是否能够解决这个问题。如果问题仍然存在,请提供更多的代码细节,我会尽力帮助您解决问题。
