I have a local dev build on commit 

lroberts@GPU77B9:~/update-vllm-env/vllm-source/vllm$ git log -n 1
commit 5265631d15d59735152c8b72b38d960110987f10 (HEAD -> main, origin/main, origin/HEAD)
Author: Vladimir <vladimir.ovsyannikov@gmail.com>

    use a correct device when creating OptionalCUDAGuard (#2583)

and I have some local code that is a thin wrapper around LLM class

If i run this with tensor-parallel == 2 I get the following:

2.1.2+cu121

It seems there a known fix or workaround here -> https://github.com/ray-project/ray/issues/41913#issuecomment-1856452166

but it seems that pydantic version 2 is necessary for openai testing

https://github.com/vllm-project/vllm/blob/3a0e1fc070dc7482ab1c8fcdc961e5729a4cb0b3/requirements.txt#L11

is there a suggested workaround or should I manually downgrade pydantic to version lower than 2.0.0?

also meet module 'pydantic._internal' has no attribute '_model_construction' in the newest dev ver

simon-mo commented 9 months ago

Looks like this is fixed in Ray 2.9 https://github.com/ray-project/ray/issues/41913#issuecomment-1858319354. Try upgrading Ray? We will make sure to lower bound the Ray version as well.

That seems to be a different issue, please open another ticket and I can try reproducing it.

Update, it did try to reproduce it. With the latest main branch:

as a work around I think you could pass the flag --disable-custom-all-reduce to not use those custom all-reduce kernels.

simon-mo commented 8 months ago

I believe #2642 might fix "resource already mapped", please try with latest main, sorry about the back and forth.

lroberts7 commented 8 months ago

@simon-mo This works for me: python -m vllm.entrypoints.openai.api_server --model TheBloke/Mistral-7B-Instruct-v0.2-AWQ --quantization awq --dtype auto --host 0.0.0.0 --port 8081 --tensor-parallel-size 2
