🐛 Describe the bug

offline_inference.py example crashes with tensor_parallel_size=2.

from vllm import LLM, SamplingParams

# Sample prompts.
prompts = [
    "Hello, my name is",
    "The president of the United States is",
    "The capital of France is",
    "The future of AI is",
]
# Create a sampling params object.
sampling_params = SamplingParams(temperature=0.8, top_p=0.95)

# Create an LLM.
llm = LLM(model="facebook/opt-125m", tensor_parallel_size=2)
# Generate texts from the prompts. The output is a list of RequestOutput objects
# that contain the prompt, generated text, and other information.
outputs = llm.generate(prompts, sampling_params)
# Print the outputs.
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")

Also, if I hack the bad return value to be what I think it expected, I run into this backtrace later in the execution.

@jikunshang are these issues addressed in #5685?

jikunshang · 2024-07-25T02:15:00Z

@jikunshang are these issues addressed in #5685?

yes, I have fixed tensor parallel support issue, please try this PR.

@jikunshang are these issues addressed in #5685?

yes, I have fixed tensor parallel support issue, please try this PR.

I have tested it on my system and it does indeed work with tp>1. Thanks! I hope it can be merged and made available in a future release.

raffenet · 2024-08-06T16:55:30Z

@jikunshang another bit of info. Running llama-2-7b with tensor parallel 2 and 4 works on my system, but on the same system trying to running llama-3-8b with with tp=2 results in this error. Is there anything I should try?

@raffenet Thanks for your evaluation. Current ipex kernel do not support GQA yet, which is widely used in latest models like llama3-8b, llama-2-70b. (I am not certain about llama-2-13b)
We have verified GQA functionality with an internal version ipex. Next ipex release will fix this issue and should be end of this month.

GQA support for vLLM will be available in coming 2.3.110 IPEX release.

GQA support for vLLM will be available in coming 2.3.110 IPEX release.

Thanks! I look forward to trying it.

Hi, When I run vllm-xpu with Qwen2. I met the same error with GQA.

  File "/workspace/vllm/vllm/_ipex_ops.py", line 158, in rotary_embedding
    ipex.llm.functional.rotary_embedding(query_rot, key_rot, sin, cos,
  File "/usr/local/lib/python3.10/dist-packages/intel_extension_for_pytorch/llm/functional/fusions.py", line 47, in rotary_embedding
    return RotaryEmbedding.apply_function(
  File "/usr/local/lib/python3.10/dist-packages/intel_extension_for_pytorch/llm/modules/mha_fusion.py", line 119, in apply_function
    query, key = runtime_module.rotary_embedding(
  File "/usr/local/lib/python3.10/dist-packages/intel_extension_for_pytorch/transformers/models/xpu/fusions/mha_fusion.py", line 79, in rotary_embedding
    torch.ops.torch_ipex.apply_rotary_embedding_half_qk(
  File "/usr/local/lib/python3.10/dist-packages/torch/_ops.py", line 692, in __call__
    return self._op(*args, **kwargs or {})
RuntimeError: The size of tensor a (2) must match the size of tensor b (14) at non-singleton dimension 2

I am wondering when will the 2.3.110 IPEX be released.

jikunshang · 2024-09-14T08:31:05Z

ipex 2.3 is released and related code change is merged in vllm main branch, issues in this thread should be resolved. Please take a try thanks!

I don't want to hijack this issue, but I'm facing the same issue as in the title. Running this on tag v0.6.2 but using the current main branch Dockerfile.xpu to build (to make sure IPEX 2.3 is being used) is still failing on my end. The build works, but the following command fails in a docker compose:

services:
  vllm-server:
    build:
      context: ./vllm
      dockerfile: Dockerfile.xpu
    container_name: vllm-server
    ports:

    restart: unless-stopped

thanks for reporting this, please try with this PR #8884.
or just set distributed_executor_backend to ray, default value is mp which is not supported.
