We are planning a release that will include vllm 0.6.2 within the next 2 weeks. In the meantime, you can try providing a requirements.txt with vllm==0.6.x and leverage a later version of vllm that way. If you go this route, you should also set OPTION_ROLLING_BATCH=vllm environment variable to force usage of vllm
