🐛 Describe the bug

I attempted to use the offline inference method to run the meta-llama/Meta-Llama-3.1-70B-Instruct model. However, after the program starts running, it hangs for a long time and then throws the following error. I can run the model in the form of an OpenAI server with tensor parallel.

Here is my code:

import os
import logging
from vllm import LLM, SamplingParams

os.environ["PT_HPU_ENABLE_LAZY_COLLECTIVES"] = "true"

prompts = [
    "The president of the United States is",
    "The capital of France is",
]

sampling_params = SamplingParams(n=1, temperature=0, max_tokens=2000)
llm = LLM(model="meta-llama/Meta-Llama-3.1-70B-Instruct", block_size=128, dtype="bfloat16", tensor_parallel_size=8)
outputs = llm.generate(prompts, sampling_params)

# Print the outputs.
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(generated_text)

Hi, this should be fixed in v1.19
