Run inference

from opensportslib.apis import VQAModel

my_model = VQAModel(
    config="opensportslib/configs/vqa/qwen3_vl_native.yaml",
    weights="YOUR_HF_REPO_ID",
)

predictions = my_model.infer(
    test_set="/path/to/test_annotations.json",
)

single_prediction = my_model.infer(
    video_path="/path/to/video.mp4",
    question="Was this a foul? What card should be given?",
)

print(predictions)
print(single_prediction)

Notes

• This repository stores a PEFT LoRA adapter, not a merged standalone base model.
• The adapter is intended for the OpenSportsLib native QwenVL VQA path driven by opensportslib/configs/vqa/qwen3_vl_native.yaml.
• The original training setup used frame-based native multimodal inputs with Qwen/Qwen3-VL-8B-Instruct.
