@vody-am If you are familiar with Chinese, could you please update the user guide in docs/zh_cn/serving/api_server_vl.md?

@lvhan028 Google translate has been working well, so yes I will give it a shot :joy:

@lvhan028 while I am here -- is there anything special one has to set to use multiple GPUs? Thus far I have experimented with one container per GPU, but it seems like there should be a way to use multiple cards. Is it the --tp setting?

[lvhan028]

Yes, by setting tp parameter

Hi, @vody-am there are linting errors, which are able to fixed by running the following commands:

pip install pre-commit
cd the/root/path/of/lmdeploy
pre-commit install .
pre-commit run --all-files
