-After training, the final model files `latest.pdparams`, `best_model.pdarams` and the training log file `train.log` will be generated in the output directory. Among them, `best_model` saves the best model under the current evaluation index, and `latest` is used to save the latest generated model, which is convenient to resume training from the checkpoint when training task is interrupted. Training can be resumed from a checkpoint by adding `-o Global.checkpoint="path_to_resume_checkpoint"` to the end of the above training scripts, as shown below.
