How to use the generation_utils.generate?
i am doing image  caption generation task，there are various implementation in different communities，which have their own improvements，i want to write a code that use the standard transformer structure，and i referenced the code inThe Annotated Transformer，now i should implement the beam_search code for sequence generation，i noticed the transformer library has a implementation in the generation_utils.generate, and there’s a lot document about text generation，but they are all pre-trained models and directly use the model.generate to generate sequence, but  how should i use the generation_utils.generate to generate caption on my own datasets based on  the standard transformer structure?  Is there any examples or tutorials that I can refer to？thanks a lot.
