Lora Adapters to GGUF conversion

[wDomin]

Hello everyone,
I'm experiencing fine tunning LLMs using Ludwig, it's going great but I'm at a bloking point.
Ludwigs fine-tuning use Lora and output an adapter.
I would love to output a gguf file for serving purposes and that's when I stumbled upon llama.cpp, but I don't really know which converter to use, every time I receive a FileNotFoundError such as:
FileNotFoundError: Can't find model in directory ../<my_project>/results/experiment_run
I'm not sure to do everything right, I tried merging it to the base model but it didn't work any better.
I'm not even sure if llama.cpp is the right tool for such a usecase.
Thx in advance.
