Extracting trained model hyperparameters

1

how to extract the model hyperparameters from the save trained pytorch model(model.pth)

2

torch.load("model.pth").
What you extract depends on what its author save.

i have used torch.save(net.state_dict()). How can i get the hyperparameters used in this model. Like optimizers

torch.save(
    dict(
        model=your_state_dict,
        optimizer=your_optimizer,
        epoch=your_epoch,
        other hyperparameters,
    ),
    save_file
)

Thank you for the answer.
