Libraries

How to use OraRL/Video-ORA-4B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="OraRL/Video-ORA-4B")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("OraRL/Video-ORA-4B")
model = AutoModelForMultimodalLM.from_pretrained("OraRL/Video-ORA-4B", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	# Reproduce the OraRL Environment

	OraRL uses one reproducible software stack for policy optimization and
	task-native evaluation. The released configuration was validated on NVIDIA
	H20/Hopper GPUs with CUDA 12.9 and includes both runtimes in this repository.

	## Requirements

	- Linux with Conda available in `PATH`
	- NVIDIA GPU with a recent driver
	- CUDA 12.9-compatible hardware for the paper-matched environment

	CUDA 12.9 GA officially requires NVIDIA Linux driver 575.51.03 or newer.
	Other NVIDIA GPUs may work, but the published setup was validated on H20.

	## Install the pinned stack

	```bash
	bash scripts/create_conda_env.sh
	conda activate orarl

	python scripts/check_environment.py \
	--require-gpu \
	--model /path/to/local/model
	```

	The installer pins Python 3.11, PyTorch 2.10.0+cu129, Transformers 5.5.4,
	vLLM 0.19.1, FlashAttention 2.8.3, and the remaining packages in
	`requirements-cu129.txt`. The final editable install exposes the `orarl-*`
	commands and the bundled `verl` trainer package from this checkout; do not
	install an unrelated `verl` release from PyPI over it.

	## Validate an evaluation-only node

	If a node will only run evaluation, skip the training-side checks:

	```bash
	bash scripts/create_conda_env.sh --evaluation-only
	conda activate orarl

	python scripts/check_environment.py --evaluation-only
	```

	## Verify the release checkout

	Run the release checks before allocating a long job:

	```bash
	python scripts/check_release.py
	python -m pytest -q
	ruff check .
	```

	On a paper-matched H20 node, add `--require-gpu --require-h20` to
	`scripts/check_environment.py`. Use the same source revision and environment on
	every node of a distributed run.

	Continue with [Training](training.md) or [Evaluation](evaluation.md).
