failed to run benchmark for bitnet_b1_58

I followed the instructions in https://github.com/microsoft/BitNet?tab=readme-ov-file#benchmark

I downloaded bitnet_b1_58-large, however running the benchmark with
python utils/generate-dummy-bitnet-model.py models/bitnet_b1_58-large --outfile models/dummy-bitnet-125m.tl1.gguf --outtype tl1 --model-size 125M
failed:

raise NotImplementedError(f'Architecture {arch!r} not supported!') from None
NotImplementedError: Architecture 'LlamaModel' not supported!

is there a necessary dependency missing / not installed ?

Start with the benchmark instructions in the README and inspect utils/generate-dummy-bitnet-model.py, especially Model.from_model_architecture and the main entry point shown in the traceback. Determine whether the downloaded model's LlamaModel architecture should be supported or whether a dependency is missing. Done means the supplied command runs without the NotImplementedError.
