# Usage
* You can potentially add a usage example below

```python
#  convert NeMo to HF:
# the script expects a adapter_config.json file which is standard in HF:
python scripts/checkpoint_converters/lora_converters/convert_nemo_to_canonical.py \
    --nemo_lora_path nemo_style_lora_model.nemo \
    --output_path ./canonical_style_lora_model.nemo \
    --hf_format --hf_config checkpoints/bin/adapter_config.json


#  convert HF to NeMo:
# /checkpoints/bin/ is a folder containing the HF lora checkpoint (usually named adapter_model.bin)
# and a HF lora config file (usually named adapter_config.json)
python scripts/checkpoint_converters/lora_converters/convert_hf_to_canonical.py \
    --hf_lora_path /checkpoints/bin/ \
    --output_path output_dir/converted_lora.nemo \
    --nemo_config model_config.yaml
