Is openai compatible server still working?

In a fresh conda env, ater pip install, the following command (mentioned in this PR) is no longer working.

python -m mii.entrypoints.openai_api_server     --model "mistralai/Mistral-7B-Instruct-v0.1"     --port 3000     --host 0.0.0.0

There are at least problems:

Extra deps are not included, but needed: shortuuid, uvicorn, ...
pydantic related. See logs below.

python -m mii.entrypoints.openai_api_server     --model "mistralai/Mistral-7B-Instruct-v0.1"     --port 3000     --host 0.0.0.0
