When I use fastchat to integrate vllm, I get the error "TypeError: top_k must be an integer, got float". The reason is that vllm 0.5.5 has added a BUGFIX #7227, check top_k must be an integer。For fastchat, the default value of top_k in vllm_worker.py is set to -1.0.

I can confirm. Changing from 1.0 to 1 fixes this.
