Hi everyone !  
When I use model end2end model as (T5, MBart,…) for task (keyphrase abstractiion) after I use model.generate(…) to gen list keypharse separated by semi-colon  
Examples: _list\_keypharse:_ **language model;keyphrase generation;new pre-training objective;pre-training setup;**

- I only can control max\_length of list\_keypharse not control max\_length of a keypharse(examples:new pre-training objective ( i want 2 token not 3 token)) in list\_keypharse

> How I can control and handle problems above? Thanks u everyoneThis text will be hidden
