Hi, ayyylol.

When I executed convert_hf_to_gguf.py, I faced the following warnings.

WARNING:hf-to-gguf:**************************************************************************************
WARNING:hf-to-gguf:** WARNING: The BPE pre-tokenizer was not recognized!
WARNING:hf-to-gguf:** There are 2 possible reasons for this:

So, I added the following codes in convert_hf_to_gguf.py according to the warnings and the gguf file was created successfully.

To make llama.cpp support the chat template of EXAONE-3.0-7.8B-Instruct, I added the following codes in src/llama.cpp .

         return -1;

I ran the llama-cli as follows:

llama-cli -m <PATH_TO_GGUF> -p "You are EXAONE model from LG AI Research, a helpful assistant." --chat-template exaone3 -cnv

Good luck to you.

@yireun thank you very much, that is very kind of you. It works now!

I've just opened a PR that introduces support for ExaoneForCausalLM :)

@mscheong thank you!
