Error with VLLM

[didoll-john]

I started the VLLM via docker, command is:
docker run --runtime nvidia --gpus all -d --restart always -v ~/data/.cache/huggingface:/root/.cache/huggingface -v /data/LLM_models/Qwen/Qwen2-72B-Instruct-GPTQ-Int4:/data/Qwen2-72B-Instruct-GPTQ-Int4 -p 8000:8000 --ipc=host vllm/vllm-openai:latest --served-model-name Qwen2-72B-Instruct-GPTQ-Int4 --model /data/Qwen2-72B-Instruct-GPTQ-Int4 --tensor-parallel-size 4
do the curl test:
curl http:https://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{ "model": "Qwen2-72B-Instruct-GPTQ-Int4", "messages": [ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "give me the answer of 1+1"} ] }'
it works well.
{"id":"cmpl-e44f7f809f5b4ebc82eff1e96c55ad1b","object":"chat.completion","created":1718184574,"model":"Qwen2-72B-Instruct-GPTQ-Int4","choices":[{"index":0,"message":{"role":"assistant","content":"The answer to 1 + 1 is 2.","tool_calls":[]},"logprobs":null,"finish_reason":"stop","stop_reason":null}],"usage":{"prompt_tokens":28,"total_tokens":41,"completion_tokens":13}}
Then I use it in the dspy like:
vllm_qwen = dspy.HFClientVLLM(model="Qwen2-72B-Instruct-GPTQ-Int4", port=8000, url="http:https://localhost")
the error code is:
Failed to parse JSON response: {"object":"error","message":"The model Qwen2-72B-Instruct-GPTQ-Int4 does not exist.","type":"NotFoundError","param":null,"code":404}
then I try to use it like this:
vllm_qwen = dspy.OpenAI(model="Qwen2-72B-Instruct-GPTQ-Int4", api_base="http:https://localhost:8000/v1", api_key='EMPTY')
got another error code:
openai.NotFoundError: Error code: 404 - {'detail': 'Not Found'}

Could it make sense to look at the container logs? docker logs <container_id>

above is the log when I use:
vllm_qwen = dspy.HFClientVLLM(model="Qwen2-72B-Instruct-GPTQ-Int4", port=8000, url="http:https://localhost")
got the error:
Failed to parse JSON response: {"object":"error","message":"The model Qwen2-72B-Instruct-GPTQ-Int4 does not exist.","type":"NotFoundError","param":null,"code":404}

you can see that there is no exactly log for this request.

[didoll-john]

And I found that I can use it as openai api now, the point is:
vllm_qwen = dspy.OpenAI(model="Qwen2-72B-Instruct-GPTQ-Int4", api_base="http:https://localhost:8000/v1/", api_key='EMPTY')
There should be a "/" after "v1"

I will try openAI API with VLLM

the solution worked for hugging face models which could be updated into:
