How to convert it to GGUF/GGML for general use?

Sorry for this dummy question but I did search for some answers and try before.
Using llama.cpp
```shell
python ./convert-hf-to-gguf.py \
../../deepseek-vl-7b-chat \
--outtype f16 \
--outfile ../../deepseek-vl-7b-chat/deepseek-v1-7b-chat.gguf
```
returned
> Loading model: deepseek-vl-7b-chat
Traceback (most recent call last):

File "/home/zhangyuanfeng/software/ollama/llm/llama.cpp/./convert-hf-to-gguf.py", line 2079, in main
model_class = Model.from_model_architecture(hparams["architectures"][0])
File "/home/zhangyuanfeng/software/ollama/llm/llama.cpp/./convert-hf-to-gguf.py", line 215, in from_model_architecture
raise NotImplementedError(f'Architecture {arch!r} not supported!') from None
NotImplementedError: Architecture 'MultiModalityCausalLM' not supported!

So is there any feasible method? Thx.
