I downloaded this model : https://huggingface.co/speechbrain/asr-whisper-medium-commonvoice-it

But when trying to convert it to gguf I get :

(.venv) raphy@raohy:~/whisper.cpp/models/italianasrmedium$ python3 ../llama.cpp/convert_hf_to_gguf.py . --outfile italian-asr-medium.gguff --outtype f16
INFO:hf-to-gguf:Loading model:

    model_architecture = hparams["architectures"][0]
                         ~~~~~~~^^^^^^^^^^^^^^^^^
KeyError: 'architectures'

How to make it work?
