Llama2 转换模型权重以使用 Hugging Face 运行时出错

Question

我正在按照此处列出的步骤进行操作https://ai.meta.com/blog/5-steps-to-getting-started-with-llama-2/ 我已经能够完成这几个步骤。但是，在尝试遵循“将模型权重转换为使用 Hugging Face 运行”步骤时，出现以下错误。

命令：

pip install protobuf && python3 $TRANSFORM --input_dir ./llama-2-7b-chat --model_size 7B --output_dir ./llama-2-7b-chat-hf --llama_version 2

错误：

Traceback (most recent call last):

    raise JSONDecodeError("Expecting value", s, err.value) from None
