Llama-2-7b-hf-4bit_g64-HQQ

This is a version of the LLama-2-7B-hf model quantized to 4-bit via Half-Quadratic Quantization (HQQ): https://mobiusml.github.io/hqq_blog/

To run the model, install the HQQ library:

#This model is deprecated and requires old versions
pip install hqq==0.1.8
pip install transformers==4.46.0

and use it as follows:

Python

model_id = 'mobiuslabsgmbh/Llama-2-7b-hf-4bit_g64-HQQ'

from hqq.engine.hf import HQQModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(model_id)
model     = HQQModelForCausalLM.from_quantized(model_id)

Limitations:
-Only supports single GPU runtime.
-Not compatible with HuggingFace's PEFT.
