how to solve this debug

[Learneducn]

Hello, excuse me. When I follow the tutorial and use your script to convert the llama-2-7b-hf model, the following error always appears. I don’t know how to solve it.
[root@localhost RobustGER-master]# sh conv_model.sh
usage: convert_lit_checkpoint.py [-h] [--config CONFIG] [--print_config[=flags]]
--checkpoint_name CHECKPOINT_NAME --out_dir OUT_DIR
--model_name MODEL_NAME
error: Validation failed: No action for key "_name_or_path" to check its value.
