problems with the OpenEntity Task(Typing)

[Jajison]

after convert the pretrain model by the transformer.convert_roberta_original_pytorch_checkpoint_to_pytorch, i got config.json and pytorch_model.bin. Then, i want to try the OpenEntity task, i set as this script '--model_name_or_path ./model_convert/' , but i got a error as the following

Did I miss some files or some settiings?
