Trainer class and compute_metrics
Hello!I am doing summarization tasks and when I am looking through the example of summarizationlink. Incompute_metricsfunction. The tokenizer is defined in the same namespace before. But if I  want to another scripts to storecompute_metricsfunction. How do I modify the function when it comes to tokenizer, since I pass it to Trainer. I just do not  like everything in themain function.Thanks
