Max Input and Output length

[shashank140195]

In the finetine_for_summarization.py, why max_source_length, train_max_target_length, and eval_max_target_length is set to default 510? Is this the max the BioMedLM can take as Input and only generate max 510 tokens? As soon as I increase the value above this default value, I get the error.

max_source_length: Optional[int] = field( default=510, metadata={"help": "the max source length of summarization data. "} ) train_max_target_length: Optional[int] = field( default=510, metadata={"help": "the max target length for training data. "} ) eval_max_target_length: Optional[int] = field( default=510, metadata={"help": "the max target length for dev data. "}

The model was trained with a fixed context length of 1024, so the source, target and extra tokens have to fit within that size.

Makes Sense. thank you.
