🐛 Describe the bug
I'm trying to run MPT-7B with tp_size=2 on H100 GPUs. Here is the code snippet I'm running:
from vllm import LLM, SamplingParams
# Create a sampling params object.
sampling_params = SamplingParams(temperature=0.8, top_p=0.95, max_tokens=300)
# Create an LLM.
model_name = "mosaicml/mpt-7b"
llm = LLM(model=model_name, trust_remote_code=True, tensor_parallel_size=2) #, enforce_eager=True)
# 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(["Write a poem on spiders."], sampling_params)
print(outputs)
The initialization step LLM() is just stuck and then shows a socket timeout error. Full trace here:

Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.
WARNING 03-26 18:23:57 llm_engine.py:181] The tokenizer's vocabulary size 50277 does not match the model's vocabulary size 50432. This might cause an error in decoding. Please change config.json to match the tokenizer's vocabulary size.
