Error in Question Answering on SQUAD

Beginners
1

I tried to run the question answering on squad dataset notebook (How to fine-tune a model on question answering)
but when i run this block

trainer = Trainer(
    model,
    args,
    train_dataset=tokenized_datasets["train"],
    eval_dataset=tokenized_datasets["validation"],
    data_collator=data_collator,
    tokenizer=tokenizer,
)

I get this error: Repository Not Found for url: https://huggingface.co/api/models//distilbert-base-uncased-finetuned-squad.
can anyone know how to solve it?
