服务器使用API_PORT=8000 CUDA_VISIBLE_DEVICES=0 llamafactory-cli api examples/inference/llama3.yaml，正常启动，无报错；

终端调用代码：
from openai import OpenAI
client = OpenAI(api_key="0",base_url="http://服务器IP:8000/v1")
messages = [{"role": "user", "content": "Who are you?"}]
result = client.chat.completions.create(messages=messages, model="服务器上模型地址")
print(result.choices[0].message)

问题描述：服务器正常打印info，显示message，但终端无响应。
尝试排错：1、在服务器上直接调用API，修改ip为0.0.0.0，仍无响应无报错；
2、直接使用transformers.pipeline调用预训练模型，模型正常推理，预训练文件正常
