Reproduction

按照文章 https://zhuanlan.zhihu.com/p/695287607 直到启动API Server

CUDA_VISIBLE_DEVICES=0 API_PORT=8000 llamafactory-cli api \
    --model_name_or_path /root/workspace/models-modelscope/Meta-Llama-3-8B-Instruct \
    --adapter_name_or_path ./saves/LLaMA3-8B/lora/sft \
    --template llama3 \
    --finetuning_type lora

由于我的环境需要配置root_path，所以服务无法正常运行，root_path 文档（FastAPI）请参考： https://fastapi.tiangolo.com/zh/advanced/behind-a-proxy/

Expected behavior
