OSError: Can't load tokenizer for 'meta-llama/Llama-2-7b-chat-hf'.

Thank you for your wonderful work, but I had some issues running python minigpt4_video_inference.py on ubuntu system： Loading LLAMA

OSError: Can't load tokenizer for 'meta-llama/Llama-2-7b-chat-hf'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure 'meta-llama/Llama-2-7b-chat-hf' is the correct path to a directory containing all relevant files for a LlamaTokenizer tokenizer.
how can I fix it？
