Checkpoint conversion

Info

This pipeline starting script is nemo_skills/pipeline/convert.py

All extra parameters are passed to one of the following scripts

• For conversion to NeMo:

  • If --model_type=llama: nemo_skills/conversion/hf_to_nemo_llama.py
  • If --model_type=qwen: nemo_skills/conversion/hf_to_nemo_qwen.py

• For conversion to HuggingFace:

  • If --model_type=llama: nemo_skills/conversion/nemo_to_hf_llama.py
  • If --model_type=qwen: nemo_skills/conversion/nemo_to_hf_qwen.py

You only need to convert models if you want to use NeMo-Aligner for training. All other server and training backends should work with HuggingFace format.

To convert the checkpoint from one format to another use a command like this

ns convert \
    --cluster=slurm \
    --input_model=/hf_models/Meta-Llama-3.1-70B-Instruct \
    --output_model=/nemo_models/llama3.1-70b-instruct \
    --convert_from=hf \
    --convert_to=nemo \
    --model_type=llama \
    --num_gpus=8 \
    --hf_model_name=meta-llama/Meta-Llama-3.1-70B-Instruct

You can provide any extra arguments that will be passed directly to the underlying conversion scripts.
