When saving a model for inference, it is only necessary to save the trained model’s learned parameters. Saving the model’s state_dict with the torch.save() function will give you the most flexibility for restoring the model later, which is why it is the recommended method for saving models.. A common PyTorch convention is to save models using either a .pt or .pth file extension.
