This could be because of an issue with the checkpoint, or because your version of Transformers is out of date.

Mar 03 01:14:38 CES-AI vllm[3250530]: (APIServer pid=3250530) You can update Transformers with the command pip install --upgrade transformers. If this does not work, and the checkpoint is very new, then there may not be a release version that supports this model yet. In this case, you can get the most up-to-date code by installing Transformers from source with the command pip install git+https://github.com/huggingface/transformers.git [type=value_error, input_value=ArgsKwargs((), {'model': ...rocessor_plugin': None}), input_type=ArgsKwargs]
