llm-jp-eval-mm

llm-jp-eval-mm is a lightweight framework for evaluating visual-language models across various benchmark tasks, mainly focusing on Japanese tasks.

Getting Started

You can install llm-jp-eval-mm from GitHub or via PyPI.

• Option 1: Clone from GitHub (Recommended)

git clone [email protected]:llm-jp/llm-jp-eval-mm.git
cd llm-jp-eval-mm
uv sync

• Option 2: Install via PyPI

pip install eval_mm

To use LLM-as-a-Judge, configure your OpenAI API keys in a.env file:

• For Azure: Set AZURE_OPENAI_ENDPOINT and AZURE_OPENAI_KEY
• For OpenAI: Set OPENAI_API_KEY

If you are not using LLM-as-a-Judge, you can assign any value in the .env file to bypass the error.

Usage

To evaluate a model on a task, run the following command:

uv sync --group normal
uv run --group normal python examples/sample.py \
  --model_id llava-hf/llava-1.5-7b-hf \
  --task_id japanese-heron-bench  \
  --result_dir result  \
  --metrics heron-bench \
  --judge_model gpt-4o-2024-11-20 \
  --overwrite

The evaluation results will be saved in the result directory:

result
├── japanese-heron-bench
│   ├── llava-hf
│   │   ├── llava-1.5-7b-hf
│   │   │   ├── evaluation.jsonl
│   │   │   └── prediction.jsonl

To evaluate multiple models on multiple tasks, please check eval_all.sh.

Hello World Example

You can integrate llm-jp-eval-mm into your own code. Here's an example:

from PIL import Image
from eval_mm import TaskRegistry, ScorerRegistry, ScorerConfig

class MockVLM:
    def generate(self, images: list[Image.Image], text: str) -> str:
        return "宮崎駿"

task = TaskRegistry.load_task("japanese-heron-bench")
example = task.dataset[0]

input_text = task.doc_to_text(example)
images = task.doc_to_visual(example)
reference = task.doc_to_answer(example)

model = MockVLM()
prediction = model.generate(images, input_text)

scorer = ScorerRegistry.load_scorer(
    "rougel",
    ScorerConfig(docs=task.dataset)
)
result = scorer.aggregate(scorer.score([reference], [prediction]))
print(result)
# AggregateOutput(overall_score=5.128205128205128, details={'rougel': 5.128205128205128})

Leaderboard

To generate a leaderboard from your evaluation results, run:

python scripts/make_leaderboard.py --result_dir result

This will create a leaderboard.md file with your model performance:

Model	Heron/LLM	JVB-ItW/LLM	JVB-ItW/Rouge
llm-jp/llm-jp-3-vila-14b	68.03	4.08	52.4
Qwen/Qwen2.5-VL-7B-Instruct	70.29	4.28	29.63
google/gemma-3-27b-it	69.15	4.36	30.89
microsoft/Phi-4-multimodal-instruct	45.52	3.2	26.8
gpt-4o-2024-11-20	93.7	4.44	32.2

The official leaderboard is available here

Supported Tasks

Managing Dependencies

We use uv’s dependency groups to manage each model’s dependencies.

For example, to use llm-jp/llm-jp-3-vila-14b, run:

uv sync --group vilaja
uv run --group vilaja python examples/VILA_ja.py

See eval_all.sh for the complete list of model dependencies.

When adding a new group, remember to configure conflict.

Browse Predictions with Streamlit

uv run streamlit run scripts/browse_prediction.py -- --task_id japanese-heron-bench --result_dir result --model_list llava-hf/llava-1.5-7b-hf

Development

Adding a new task

To add a new task, implement the Task class in src/eval_mm/tasks/task.py.

Adding a new metric

To add a new metric, implement the Scorer class in src/eval_mm/metrics/scorer.py.

Adding a new model

To add a new model, implement the VLM class in examples/base_vlm.py

Adding a new dependency

Install a new dependency using the following command:

uv add <package_name>
uv add --group <group_name> <package_name>

Testing

Run the following commands to test tasks, metrics, and models::

bash test.sh
bash test_model.sh

Formatting and Linting

Ensure code consistency with:

uv run ruff format src
uv run ruff check --fix src

Releasing to PyPI

To release a new version:

git tag -a v0.x.x -m "version 0.x.x"
git push origin --tags

Updating the Website
