This script downloads the tokenizer models of the specified models from Huggingface and
generates the get_vocab_base_pre() function for convert_hf_to_gguf.py
/!\\ It is intended to be used by contributors and is not meant to be run by end users
This is necessary in order to analyze the type of pre-tokenizer used by the model and
provide the necessary information to llama.cpp via the GGUF header in order to implement
the same pre-tokenizer.
ref: https://github.com/ggml-org/llama.cpp/pull/6920
Instructions:
- Add a new model to the "models" list
- Run the script with your huggingface token
By default, token will be read from ~/.cache/huggingface/token
- The convert_hf_to_gguf.py script will have had its get_vocab_base_pre() function updated
- Update llama.cpp with the new pre-tokenizer if necessary
