从日志中可以看到，问题出在async_llm_engine.py文件的第45行。具体错误信息如下：

Unable to get power limit for GPU 0. Status:Success, value:0.000000

这意味着无法获取GPU 0的电源限制。可能的原因是Triton服务器没有正确配置GPU支持。请检查Triton服务器的配置文件(例如config.pbtxt),确保其中包含以下内容：

name: "localhost"
platform: "nvidia_tesla_k80"
max_batch_size: 0
gpu_device_id: 0

如果问题仍然存在，请尝试更新Triton服务器和NVIDIA驱动程序到最新版本。
