Fine-tune BERTForMaskedLM

Hello,

I am doing a project on spelling correction. I used pre-trained “bert-base-cased” model. However, the results are not that accurate. Therefore, I planned to fine-tune the BERT for Masked LM task. I couldn’t find any examples for fine-tuning BERT model for Masked LM. I tried to use “run_language_modeling.py” for fine-tuning. But, I came across with the following error:

C:\Users\ravida6d\spell_correction\transformers\examples\language-modeling>python run_language_modeling.py --output_dir ="C:\\Users\\ravida6d\\spell_correction\\contextualSpellCheck\\fine_tune\\" --model_type = bert --model_name_or_path = bert-base-cased --do_train --train_data_file =$TRAIN_FILE --do_eval --eval_data_file =$TEST_FILE –mlm

  FutureWarning,

    raise ValueError(f"Some specified arguments are not used by the HfArgumentParser: {remaining_args}")
ValueError: Some specified arguments are not used by the HfArgumentParser: ['bert', 'bert-base-cased']

I am not understanding how to use this script. Can anyone give some information for understanding the fine-tuning of BERT Masked LM.
