How would you like to use vllm

I am trying to run a Mistral with vllm with this command

python -u -m vllm.entrypoints.openai.api_server --host 0.0.0.0 --model mistralai/Mistral-7B-Instruct-v0.2 --max-model-len 15000 --port 80 --enforce-eager --device cuda --engine-use-ray --tokenizer mistralai/Mistral-7B-Instruct-v0.2 --tokenizer-mode auto

I have Nvidia A10 running and if i will not use ray, everything works perfectly, but if i activate ray i got this error File "/usr/local/lib/python3.10/dist-packages/uvicorn/protocols/http/httptools_impl.py", line 411, in run_asgi result = await app( # type: ignore[func-returns-value] File "/usr/local/lib/python3.10/dist-packages/uvicorn/middleware/proxy_headers.py", line 69, in __call__ return await self.app(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/fastapi/applications.py", line 1054, in __call__ await super().__call__(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/applications.py", line 123, in __call__ await self.middleware_stack(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/middleware/errors.py", line 186, in __call__ raise exc File "/usr/local/lib/python3.10/dist-packages/starlette/middleware/errors.py", line 164, in __call__ await self.app(scope, receive, _send) File "/usr/local/lib/python3.10/dist-packages/starlette/middleware/cors.py", line 83, in __call__ await self.app(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/middleware/exceptions.py", line 62, in __call__ await wrap_app_handling_exceptions(self.app, conn)(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/_exception_handler.py", line 64, in wrapped_app raise exc File "/usr/local/lib/python3.10/dist-packages/starlette/_exception_handler.py", line 53, in wrapped_app await app(scope, receive, sender) File "/usr/local/lib/python3.10/dist-packages/starlette/routing.py", line 758, in __call__ await self.middleware_stack(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/routing.py", line 778, in app await route.handle(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/routing.py", line 299, in handle await self.app(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/routing.py", line 79, in app await wrap_app_handling_exceptions(app, request)(scope, receive, send) File "/usr/local/lib/python3.10/dist-packages/starlette/_exception_handler.py", line 64, in wrapped_app raise exc File "/usr/local/lib/python3.10/dist-packages/starlette/_exception_handler.py", line 53, in wrapped_app await app(scope, receive, sender) File "/usr/local/lib/python3.10/dist-packages/starlette/routing.py", line 74, in app response = await func(request) File "/usr/local/lib/python3.10/dist-packages/fastapi/routing.py", line 278, in app raw_response = await run_endpoint_function( File "/usr/local/lib/python3.10/dist-packages/fastapi/routing.py", line 191, in run_endpoint_function return await dependant.call(**values) File "/usr/local/lib/python3.10/dist-packages/vllm/entrypoints/openai/api_server.py", line 168, in create_chat_completion generator = await openai_serving_chat.create_chat_completion( File "/usr/local/lib/python3.10/dist-packages/vllm/entrypoints/openai/serving_chat.py", line 68, in create_chat_completion request, self.engine.get_tokenizer())) File "/usr/local/lib/python3.10/dist-packages/vllm/engine/async_llm_engine.py", line 337, in get_tokenizer return self.engine.tokenizer.tokenizer File "/usr/local/lib/python3.10/dist-packages/ray/actor.py", line 1368, in __getattr__ raise AttributeError( AttributeError: 'ActorHandle' object has no attribute 'tokenizer'

Hi. @dmayboroda This should be resolved by #3301.
