🐛 Describe the bug
In short: With default max_num_batched_tokens, using compile cache causes error; with max_num_batched_tokens=1, the error will always appear no matter using compile cache or not.
I'm using this script for the latest commit 1fb4217a052189feb8709b67bb3209ab316d13b7 .
from vllm import LLM, SamplingParams
if __name__ == "__main__":
llm = LLM(
model="Qwen/Qwen3-8B",
)
prompts = ["""<|im_start|>system
You are Qwen, created by Alibaba Cloud. You are a helpful assistant.<|im_end|>
<|im_start|>user
Give me a short introduction to large language model.<|im_end|>
<|im_start|>assistant"""]
sampling_params = SamplingParams(max_tokens=1024)
outputs = llm.generate(prompts, sampling_params)
print(len(outputs), " outputs generated")
for index, output in enumerate(outputs):
print(f"prompt {index}: ", output.prompt)
print(f"output {index}: ", output.outputs[0].text)
print("-" * 100)When I use:
VLLM_DISABLE_COMPILE_CACHE=1 python offline.py
The program runs without error.
When I use:
python offline.py
I'll get error:
https://gist.github.com/NorthmanPKU/f13134a6dccdf363ab01f051a25de093
By changing the script to use max_num_batched_tokens=1, I'll get error in both using/not using cache cases:
from vllm import LLM, SamplingParams
if __name__ == "__main__":
llm = LLM(
model="Qwen/Qwen3-8B",
max_num_batched_tokens=1
