# To run this recipe, please use the following command. Replace --nproc-per-node=8 with the number of GPUs on your node:
# torchrun --nproc-per-node=8 examples/llm_finetune/finetune.py --config examples/llm_finetune/nemotron/nemotron_nano_v3_hellaswag.yaml
# For multi-node, use the following:
# torchrun --nproc-per-node=8 --nnodes=2 examples/llm_finetune/finetune.py --config examples/llm_finetune/nemotron/nemotron_nano_v3_hellaswag.yaml
