Usage:

You can use the model with NeMo Aligner following SteerLM training user guide.

  1. Spin up an inference server within the NeMo container (docker pull nvcr.io/nvidia/nemo.24.05.llama3.1)
HF_HOME=<YOUR_HF_HOME_CONTAINING_TOKEN_WITH_LLAMA31_70B_ACCESS> \
python /opt/NeMo-Aligner/examples/nlp/gpt/serve_reward_model.py \
      rm_model_file=Llama-3.1-Nemotron-70B-Reward \
      trainer.num_nodes=1 \
      trainer.devices=8 \
      ++model.tensor_model_parallel_size=8 \
      ++model.pipeline_model_parallel_size=1 \
      inference.micro_batch_size=2 \
      inference.port=1424
  1. Annotate data files using the served reward model. As an example, this can be the Open Assistant train/val files. Then follow the next step to train a SteerLM model based on SteerLM training user guide .

Please note that this script rounds the predicted floats to the nearest int (between 0 and 4 inclusive), as it's meant for SteerLM training. For other use cases (e.g. reward bench measurement, response filtering/ranking), we recommend using the floats directly, which can be done by commenting out two lines of code in NeMo-Aligner

python /opt/NeMo-Aligner/examples/nlp/data/steerlm/preprocess_openassistant_data.py --output_directory=data/oasst
python /opt/NeMo-Aligner/examples/nlp/data/steerlm/attribute_annotate.py \
      --input-file=data/oasst/train.jsonl \
      --output-file=data/oasst/train_labeled.jsonl \
      --port=1424
  1. Alternatively, this can be any conversational data file (in .jsonl) in the following format, where each line looks like
{
    "conversations": [
              {"value": <user_turn_1>, "from": "User", "label": None},
              {"value": <assistant_turn_1>, "from": "Assistant", "label": <formatted_label_1>},
              {"value": <user_turn_2>, "from": "User", "label": None},
              {"value": <assistant_turn_2>, "from": "Assistant", "label": <formatted_label_2>},
          ],
    "mask": "User"
}

Ideally, each <formatted_label_n> refers to the ground truth label for the assistant turn but if they are not available, we can also use helpfulness:-1. It must not be None or an empty string.
