  1. Create a new conda environment and install vLLM with Python 3.12
  2. Copy vllm_inference.py and run.
  3. Installed model through vllm.
  4. Error:

In rare cases this process can exit before this point and block the progress of another member of the process group. This constraint has always been present,  but this warning has only been added since PyTorch 2.4 (function operator())

Thanks for the reply, I have tried to update the vllm version by running
pip install vllm==0.5.4

And here's the environment packages, updated:

你好，是不是你的模型没有下载成功？可以试试先把模型下载到本地然后用本地路径载入vllm。
