custom prepare_inputs_for_generation for generation 
Hi
I need to change  model_inputs used for the generation, I am using T5ForConditionalGeneration which has extra input parameter and this needs to be passed in each time I call model.generate(), I cannot see how to rewrite the generate function to also pass this argument, could you provide me with some explanation:

thanks

solved with implementing it inside the model of T5ForConditionalGeneration  thanks
