Llama 405B NeMo version
In the models catalog [here](https://catalog.ngc.nvidia.com/models) I could only find Llama 8B and 70B. Is there a 405B version available somewhere? 

I tried converting the HF model to NeMo using the `convert_llama_hf_to_nemo.py` script but the code runs out of memory even on a 1TB system. Is there a workaround for this?
