 ## Stage 2:  Top-k Models Averaging
 After training the model,  we need to get the final model for testing and inference. In every epoch, the model checkpoint is saved, so we can choose the best model from them based on the validation loss or we can sort them and average the parameters of the top-k models to get the final model.  We can use stage 2 to do this, and the code is shown below:
