chunk_content: _align_labels function to the dataset:
  
  
  	Copied
  tokenized_bionlp = bionlp.map(tokenize_and_align_labels, batched=True)
  Finally, create a data collator to pad the examples to the longest length in a batch:
  
  
  	Copied
  data_collator = DataCollatorForTokenClassification(tokenizer=tokenizer)
  
  Train
  	
  Now you’re ready to create a PeftModel. Start by loading the base roberta-large model, the number of expected labels, and the id2label and label2id dic
