can llama.cpp/convert.py support tokenizer rather than 'spm', 'bpe', 'hfft'

[woodx9]

I am trying to convert deepseek-ai/deepseek-coder-1.3b-base using llama.cpp/convert.py
with

Command

python llama.cpp/convert.py codes-hf
--outfile codes-1b.gguf
--outtype q8_0

Output:

Loading model file codes-hf/pytorch_model.bin

the "tokenizer_class": "LlamaTokenizerFast", is there a way to support it?

Try adding --vocab-type bpe as an opinion. IIRC, I had to do that for deepseek-coder models.

I try that, But I think it's not the right choice, they are two different tokenizer way after all. And I have a question of how to tokenizer them with --no-vocab

Deepseek models support is in progress:

• Deepseek coder merge #5464 (comment)
• llama : add Deepseek support #5981
• llama : add Deepseek support #5981 #6252

I have read all of them, thank You! I will see what can I do!

Looking forward to your work!

I am trying to convert https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct using llama.cpp/convert.py
I have the following error when trying to convert, similar to the error with deepseek coder mentioned above. I am not able to fix this error, can anyone help?

command:
python llama.cpp/convert.py llama3-8b --outfile llama3-8b-8k-f16.gguf --outtype f16

[professorf]

add
--vocab-type bpe
to the command line

That should fix it.

This also applies to using convert.py for converting the Meta distributed Llama3 files.

Oh, it's been awhile, but I found it!

python convert.py local/models/deepseek-ai/deepseek-coder-6.7b-instruct --vocab-type hfft --pad-vocab

This is the original command I used. You need to use the --vocab-type and --pad-vocab options. I forgot why, it was related to PR #3633. You can read the rationale for it here.

The Meta distributed Llama3 files are currently unsupported. I've been working on it all day today to see if I can figure it out.

I have no idea what model format Meta used and that's the part I'm stuck on right now. torchtext also seems to use binary formats, not plaintext BPE formats, so that's why I'm stuck at the moment.

Does hfft fit with the way Deepseek Tokenizer? I doubt it. Can you give a reason plz?

[teleprint-me]

@woodx9 I didn't create it so you'll need to read the linked rationale.
