nvidia/Alpamayo-R1-10B 4bit Model.

이모델은 자율주행 중 수집된 데이터로 이벤트를 예측하는 용도로 활용할 수 있습니다. 자율주행을 하는게 아니라 자율주행 중 특정 상황이 발생할 것을 알려주는 기능을 합니다.

Runinfo

model download  ./Alpamayo-R1-10B-4bit 
 
GPU 12G/16G Memory Run able

12G Memory is  num_frames is 1 ~ 8, over OOM
 
Transformers is 4.57.5 ( 5.0.0rc not run)

nvidia/Alpamayo-R1-10B 이 대용량 메모리를 요구하고 4bit 로 로딩하여 저장한 모델입니다.
12G 에서도 실행가능해졌습니다만  주어지는 프레임수는 1~8정도, 그 이상이면 OOM이 떨어집니다.
트랜스포머 버전 5.0.0rc에서는 동작하지 않습니다.

git clone https://github.com/NVlabs/alpamayo 하고
cd alpamayo
pip install .  로 설치해야 합니다만

pyproject.toml을 수정하는게 좋습니다.
python 3.13을 사용하면 requires-python = "==3.13.*"
transformers 와 torch를 라인을 제거하고 설치하면 설치된 버전이 교체되지 않습니다.

나는 1장의 이미지로 판독하는 것을 테스트 하려고 아래와 같은 예제를 만들었다. 데이터 로딩 없이 기본 초기화를 하여 시작점에서 시작하는 것에서 시작한다. 구동하기 위해서 최소 12G 이상인 GPU카드를 사용해야 하고, 응답속도 도 꽤 지연이 걸려 실제 자동차에 적용하기에 무리인것 같다.
