For a code like this, it keeps changing processing_class=tokenizer to "tokenizer=tokenizer", even though the parameter was renamed and even after adding the all caps comment.

    #Set up the SFTTrainer
    print("Setting up SFTTrainer...")
    trainer = SFTTrainer(
    model=model,
    train_dataset=train_dataset,
    args=sft_config,
    processing_class=tokenizer, # DO NOT CHANGE. THIS IS NOW THE CORRECT PROPERTY NAME
    )
    print("SFTTrainer ready.")
