Please provide more information on your environment by running the command at the beginning of your post (under "Your current environment"). The issue seems to come from having incompatible packages installed so you might want to reset your Python environment.

Hello, I've run into this same issue. Here's the the output of collect_env.py when I run it.

FWIW, my deps are generated using pip compile with vllm pinned to vllm>=0.5.0.post1 so they should in theory be compatible with vllm. LMK if you see anything wrong/if I can share other outputs to help debug this. Thanks!

How did you run vLLM? Can you show the command/code?

Sure, here's the "model" code. It gets initialized in a webserver from which I want to serve the model:

from typing import Any

from PIL import Image
from vllm import LLM, SamplingParams

from ai.lib.py.models.model import ModelBase

class Llava(ModelBase):
    PROMPT = "[INST] <image>\ label this. [/INST]"

    def __init__(self) -> None:
        model_id = "llava-hf/llava-v1.6-mistral-7b-hf"
        self.llm = LLM(
            model=model_id,
            trust_remote_code=True,
            max_model_len=4096,
            tensor_parallel_size=1,
            image_input_type="pixel_values",
            image_token_id=32000,
            image_input_shape="1,3,640,760",
            image_feature_size=17752,
            dtype='half',
        )
        self.sampling_params = SamplingParams(
            temperature=0.1, top_p=0.95, max_tokens=2048
        )

    def predict(self, input: Any) -> str:
        image = Image.open(input).convert("RGB").resize((640, 760))
        outputs = self.llm.generate(
            {
                "prompt": self.PROMPT,
                "multi_modal_data": {"image": image},
            },
            sampling_params=self.sampling_params,
        )
        for o in outputs:
            generated_text = o.outputs[0].text
            print(generated_text)
        return " ".join([o.outputs[0].text for o in outputs])

I got a similar issue recently and it turns out that it's because vLLM cannot allocate blocks for the model. Here, I think you set image_feature_size to a value that is too high (normally it should be around 2k or so, not 60k or 17k).

Anyways, the --image-feature-size argument has since been removed (it is now computed automatically by #6089) so you should not run into this issue anymore.

Yeah I noticed this was removed - I wasn't able to build from source unfortunately so I'm stuck on the older version. Not a huge deal, I can wait for the next pypi release. Appreciate you taking a look, thanks!

[DarkLight1337]

The next release should be just around the corner! See #5806 for more details.
