@benjamin27315k Hi
- is there a way to change the model hyperparameters (the temperature, mostly) ?
Yes, you can change the model hyperparameter directly in this file https://github.com/intel/neural-speed/blob/main/neural_speed/convert/convert_llama.py#L1159-L1176. Take llama as an example. Just modify and re-run this script to get a customized gguf file.
- is there a way to not use a tokenizer coming from HF, and instead do like llama-cpp and use the tokenizer included in the .gguf file ? (in my use case, I'd like to not depend on an external lib)
Yes. when you get a gguf model file, you can run this script
python scripts\inference.py --model_name llama2 -m ggml-model-q4_0.gguf -n 512 -p "Building a website can be done in 10 simple steps:"
This script will use the tokenizer inside of the gguf.
Thank you very much, @Zhenzhong1 ! I'll try that and keep you posted if anything goes wrong 👍
Hi @Zhenzhong1
so I tried what you advised and :

I saw all the parameters for loading the model, but not the inference parameters (temperature, top_p, etc...)

Do I need a customized .gguf file for this command line to run, or one I just downloaded as is would work (it currently doesn't : error loading model: unrecognized tensor type 10
)(ah, sorry, I'm trying to use this model : llama-2-7b-chat.Q2_K.gguf, taken from TheBloke on HF)
Nevermind my second question, I forgot it had to be Q4 ^^
Ah, and while I'm at it, when using CLI, if I get an error, it freezes the terminal. Would you have a trick to avoid that ?

@benjamin27315k just type stty echo
in command line, will be ok.

@benjamin27315k
you don't need a customized GGUF if you only want to modify inference parameters.
Inference parameters are input args, just modify them in the command line. Please check this https://github.com/intel/neural-speed/blob/main/docs/advanced_usage.md for more inference parameters.
@benjamin27315k, I will close this issue if you don't have concerns
Hello there,
I'm new to neural speed, coming from llama-cpp-python, and i encounter some problems (probably due to a misunderstanding on my side).
I don't want to flood you with issues so I'll start with my two main questions :
Thank you !
