Describe the bug

部署OPENAI 服务后，模型一直输出重复的结果

Reproduction

服务运行命令：

CUDA_VISIBLE_DEVICES=0,3,4,5 NCCL_SHM_DISABLE=1 lmdeploy serve api_server /data/workspace/models/llava-v1.6-34b --server-port 23333 --tp 4 --cache-max-entry-count 0.5 --chat-template template.json

template.json文件内容：

{
    "model_name": "llava-chatml",
    "system": "system\n",
    "meta_instruction": "You are a robot developed by lmdeploy.",
    "eosys": "\n",
    "user": "user\n",
    "eoh": "\n",
    "assistant": "assistant\n",
    "eoa": "",
    "separator": "\n",
    "capability": "chat",
    "stop_words": [""]
}

程序运行代码：

from openai import OpenAI
import sys
from qwen_test import prompts

client = OpenAI(api_key='YOUR_API_KEY', base_url='http://0.0.0.0:23333/v1')
model_name = client.models.list().data[0].id
stream = True
responses = client.chat.completions.create(
    model=model_name,
    messages=[{
        'role':
        'user',
        'content': [{
            'type': 'text',
            'text': '描述一下这张图片',
            
        }, {
            'type': 'image_url',
            'image_url': {
                'url': 'http://yanshi.jxgh.vip:8000/000000-zg119/upload/20240123/6f3a0494cc268f34b146031d73eaaaf8.jpeg',
            },
        }],
    }],
    temperature=0.1,
    stream=stream,
    # top_p=0.8
    )
if stream:
    for response in responses:
        result = response.choices[0].delta.content
        sys.stdout.write(result)
        sys.stdout.flush()
else:
    print(responses.choices[0].message.content)

程序输出结果：

Error traceback

No response

我感觉是生成参数的原因，把temperature=0.1注释掉，跑了很多次都没有重复的现象。

另外看你指定了template.json，改了meta_instruction，但是为什么要把<|im_start|>, <|im_end|>这些token去掉呢？

ollama 是怎么跑的？ 也是自定义了相同的模版，相同的生成参数跑的么？

把<|im_start|>, <|im_end|>这些token加上我也测试过，一样的错误；
把temperature=0.1注释掉，没有出现重复的输出，很奇怪，为什么temperature=0.1的设置会导致重复的输出

ollama是使用相同的prompt、图片、参数，没有自定义模板，输出结果正常
