Does VLLM currently support QWEN LoRa model ？

[qingjiaozyn]

I use the multi-LoRA for offline inference: sql_lora_path = "/home/zyn/models/slot_lora_gd"

from vllm import LLM, SamplingParams from vllm.lora.request import LoRARequest

llm = LLM(model="/home/models/dem_14b/base", enable_lora=True, trust_remote_code=True)

sampling_params = SamplingParams(temperature=0, max_tokens=256, stop=["[/assistant]"])

prompts = [ "[user] Write a SQL query to answer the question based on the table schema.\n\n context: CREATE TABLE table_name_74 (icao VARCHAR, airport VARCHAR)\n\n question: Name the ICAO for lilongwe international airport [/user] [assistant]", "[user] Write a SQL query to answer the question based on the table schema.\n\n context: CREATE TABLE table_name_11 (nationality VARCHAR, elector VARCHAR)\n\n question: When Anchero Pantaleone was the elector what is under nationality? [/user] [assistant]", ]

outputs = llm.generate(prompts, sampling_params, lora_request=LoRARequest("sql_adapter", 1, sql_lora_path))

llm = LLM(model="/home/models/dem_14b/base",

Support for this model may be added in the future. If this is important to you, please open an issue on github.

May I ask when this problem will be resolved and is there a plan

Hey, I have also encountered the same problem as you. May I ask when I can integrate qwen lora model loading? I would be appreciated if you solved this problem and let me know. I‘m concerned about this problem at present, thx.
