背景

        我在本地windoes部署ChatGLM3-bB，且希望部署后能提供HTTP server的能力。

        模型部署且启动是成功了，但是在访问生成接口/v1/chat/completions时报错failed to open nvrtc-builtins64_121.dll。

问题详细描述

找不到nvrtc-builtins64_121.dll

RuntimeError: nvrtc: error: failed to open nvrtc-builtins64_121.dll.
  Make sure that nvrtc-builtins64_121.dll is installed correctly.

github上也有人报了这个问题

解决方案

原因：pytorch和cuda版本不匹配导致的

pytorch安装时，对应的CUDA12.1

但我本地之前安装的是CUDA12.4

因此找不到12.1版本的nvrtc-builtins64_121

方案：安装多版本CUDA，再安装一个CUDA12.1
