[Version: 4.49.0] Qwen2.5-VL is not supported in vLLM because of transformers

[usun1997]

System Info

error: Model architectures Qwen2 5 VLForConditionalGeneration' failed to be inspected. Please check the logs for more details.

right now people say that they are using methods like:

1. pip install --upgrade git+https://github.com/huggingface/transformers.git@336dc69d63d56f232a183a3e7f52790429b871ef ([Bug]: Qwen2.5-VL broke due to transformers upstream changes vllm-project/vllm#13285)
2. pip install --force-reinstall git+https://github.com/huggingface/transformers.git@9985d06add07a4cc691dc54a7e34f54205c04d40 ([Bug] ValueError: Model architectures ['Qwen2_5_VLForConditionalGeneration'] failed to be inspected. Please check the logs for more details. vllm-project/vllm#12932)
3. There is a breaking change in transformers dev. You need to update vLLM to latest dev and also redownload the HF model repo. ([Bug] ValueError: Model architectures ['Qwen2_5_VLForConditionalGeneration'] failed to be inspected. Please check the logs for more details. vllm-project/vllm#12932)

I mean. This is not supposed to be like this. I can't connect to your github without a vpn, and with a vpn, I can't connect to my workspace. Could transformers team just fix the problem instead of letting people solve it by some weird method. Thanks!

Who can help?

cc @zucchini-nlp, but it would help a lot if someone could post the logs/error to help us figure out what's going on here!

Hey all! The issue is being fixed on vllm side with vllm-project/vllm#13592 afaik, the team will check compatibility with v4.49 release

That's because the qwen2.5-vl implementation in vllm 0.7.2 (the latest release, not latest commit) is still trying import Qwen2_5_VLImageProcessor which has been removed in transformers 4.49.0 release.

vLLM team is planning to make a new release including the corresponding fix (vllm-project/vllm#13286), perhaps today or tomorrow.

Hello! We have released vllm==0.7.3 - Although vllm-project/vllm#13602 didn't make it to the release, we have confirmed that our docker image and PyPI package both have transformers==4.49.0 installed and should be compatible with it!

Still not working after upgrate to vllm==0.7.3

Still not working after upgrate to vllm==0.7.3

Can you try specifying the huggingface ID (e.g, Qwen/Qwen2.5-VL-3B-Instruct) directly?

Unfortunately, I can't.. my GPU cluster do not have access to huggingface.. but I've the latest version of the model stored in this path.. .

Updates:

I managed to use the mentioned "weird" method to solve the case by using:

pip install --force-reinstall git+https://github.com/huggingface/transformers.git@9985d06add07a4cc691dc54a7e34f54205c04d40

Do you know why it can be solved? Transformers 4.49.0dev version is helpful. Here, the version 4.49.0 dev can support Qwen2.5-VL-7B, but "pip install transformers --upgrade" to get 4.49.0 version does not help.

Check your config.json file, and change the processor name in preprocessor_config.json

"image_processor_type": "Qwen2VLImageProcessor",

This should work for most cases if you have latest transformers

[igorpereirabr1]

pip install --force-reinstall git+https://github.com/huggingface/transformers.git@9985d06add07a4cc691dc54a7e34f54205c04d40

still not working for me.. Same error: ValueError: Model architectures ['Qwen2_5_VLForConditionalGeneration'] failed to be inspected. Please check the logs for more details.
