Describe the bug

I use command to deploy InterVL-78B model, could you help me find out the problem? It is ok when I use same envirnment to deploy 8B model:

CUDA_VISIBLE_DEVICES=0,1,2,3 python -m vllm.entrypoints.openai.api_server --model /root/autodl-tmp/models/InternVL3-78B --served-model-name qwen2.5-vl-72b-instruct --port=8005 --limit-mm-per-prompt image=3 --seed 0 --gpu-memory-utilization 0.92 --tensor-parallel-size 4 --max_model_len 25000 --trust-remote-code --chat-template-content-format openai

The error below:

INFO:     Started server process [3587]
INFO:     Waiting for application startup.
INFO:     Application startup complete.

[Isotr0py]

试试去掉 --chat-template-content-format openai？vLLM 应该是能自动识别chat template格式的

[YuanDaoze]

试试去掉 --chat-template-content-format openai？

我起初是没有这个参数的，报错是一样的，然后它报错提示有这个建议，我才添加上的，然后报错还是一样的

[Isotr0py]

ValueError: can only concatenate str (not "list") to str

一般这个报错就是 string 格式的 chat template 被当成 openai 格式的用了。你用的 vLLM 版本是多少？

我起初是没有这个参数的，报错是一样的，然后它报错提示有这个建议，我才添加上的，然后报错还是一样的

能提供一下复现用的 request 吗？我刚才在 v0.10.2 上用 OpenGVLab/InternVL3-78B 的 tokenizer 试了一下好像复现不出来。

我起初是没有这个参数的，报错是一样的，然后它报错提示有这个建议，我才添加上的，然后报错还是一样的

能提供一下复现用的 request 吗？我刚才在 v0.10.2 上用 OpenGVLab/InternVL3-78B 的 tokenizer 试了一下好像复现不出来。

或者你试试拉取一下最新的 checkpoint？这两天 InternVL3的仓库刚修了个chat template的issue: https://huggingface.co/OpenGVLab/InternVL3-78B/commit/4a42b163cc0e222e97b10b562eee98da6bf26077

如下是我的库版本号，我今天试试更新chat template以及最新版本的vllm再测试下，感谢兄弟！

vllm                      0.9.2+cu126              pypi_0    pypi
transformers              4.53.3                   pypi_0    pypi

如下是我的request信息,图片可以随便照一张即可，我的主要问题出现在多模态的request上，普通的文本没有问题：

    # print(image_path)
    image_url = []

    # 如果 image_path 不是列表，就将它变成一个包含单个元素的列表
    if isinstance(image_path, str):
        
        image_path = [image_path]  # 将字符串包装成列表
    for image in image_path:  # 直接遍历图像路径列表
        if image is None:  # 如果图像路径是None，跳过该项
            image_url.append(None)
            continue
        
        # 读取图像数据
        with open(image, 'rb') as image_file:
            image_data = image_file.read()
        
        # 将图像数据转换为base64编码
        image_base64 = base64.b64encode(image_data).decode('utf-8')
        
        url = f'data:image/jpeg;base64,{image_base64}'

ValueError: can only concatenate str (not "list") to str

一般这个报错就是 string 格式的 chat template 被当成 openai 格式的用了。你用的 vLLM 版本是多少？

我更新vllm版本后，InterVL3-instruct仍旧报错，并且错误原因一致,我测试了同样的调用，在InterVL3_5 一切正常,我确认模型更新好的chat-template已经是最新的版本：

Chat completion output: I'm unable to identify or verify the identities of animals in images. However, the first image shows a duck on the water, and the second one features a lion in a grassy field. If you need more detailed information about these animals, you might consult natural history books or expert resources.

可以告诉我，你的环境和机器吗？我用的A800，可能无法支持更高的CUDA版本，用不了最新的vllm，我的vllm版本是0.8.5

@YuanDaoze 你这里的 messages 是什么样的，我感觉这里应该写成 messages.extend(messages_img)

Describe the bug

I use command to deploy InterVL-78B model, could you help me find out the problem? It is ok when I use same envirnment to deploy 8B model:

CUDA_VISIBLE_DEVICES=0,1,2,3 python -m vllm.entrypoints.openai.api_server --model /root/autodl-tmp/models/InternVL3-78B --served-model-name qwen2.5-vl-72b-instruct --port=8005 --limit-mm-per-prompt image=3 --seed 0 --gpu-memory-utilization 0.92 --tensor-parallel-size 4 --max_model_len 25000 --trust-remote-code --chat-template-content-format openai

可以告诉我，你的环境和机器吗？我用的A800，可能无法支持更高的CUDA版本，用不了最新的vllm，我的vllm版本是0.8.5

我用的 vLLM 0.10.2 + CUDA12.6 + 两张 T4 卡。vLLM 0.8.5 有点老了，而且我们之前在0.9版本左右修过一些 chat template 上的 bug。🥲

@YuanDaoze 我试了一下上面的 message，应该是 system prompt 这一 part 出问题了：

    {
        'role': 'system', 
        'content': 'You are good at reasoning and problem solving. You need to help user choose the best reasoning method and ONLY give back the choosen reasoning method, for example: "1 How could I devise an experiment to help solve that problem?'
    },

去掉 system prompt 或者启动模型时加上 --chat-template-content-format string，模型都是能正常输出的。我感觉 InternVL3 model repo 里的 chat template 还是写的有点问题。🤔

{%- if messages[0]['role'] == 'system' %}{{- '<|im_start|>system\n' + messages[0]['content'] + '<|im_end|>\n' }}

Openai 格式下 vLLM 输进去 chat template 的 messsage 大概长这样：

[{'role': 'system', 'content': [{'type': 'text', 'text': 'You are good at reasoning and problem solving.'}]}, {'role': 'user', 'content': [{'type': 'text', 'text': 'What are the animals in these images?'}, {'type': 'image'}, {'type': 'image'}]}]

但是 InternVL3 里的 system 部分是按照 string 格式写的：

{%- if messages[0]['role'] == 'system' %}{{- '<|im_start|>system\n' + messages[0]['content'] + '<|im_end|>\n' }}

所以用 --chat-template-content-format openai 时， 一旦 message 里有 system prompt 的部分就会导致 list + str 的操作

谢谢，那么该如何解决这个问题呢？刚刚试了你的tokenizer的方法，但是模型似乎指令跟随能力下降了，无法输出标签？感觉很奇怪

试试换成 --chat-template-content-format string?
