## Llama-2-70b-chat-hf-2bit_g16_s128-HQQ |
|
This is a version of the LLama-2-70B-chat-hf model quantized to 2-bit via Half-Quadratic Quantization (HQQ): https://mobiusml.github.io/hqq_blog/ |
|
|
|
To run the model, install the HQQ library from https://github.com/mobiusml/hqq and use it as follows: |
|
``` Python |
|
from hqq.models.llama_hf import LlamaHQQ |
|
import transformers |
|
|
|
model_id = 'mobiuslabsgmbh/Llama-2-70b-chat-hf-2bit_g16_s128-HQQ' |
|
#Load the tokenizer |
|
tokenizer = transformers.AutoTokenizer.from_pretrained(model_id) |
|
#Load the model |
|
model = LlamaHQQ.from_quantized(model_id) |
|
``` |
|
|
|
*Limitations*: <br> |
|
-Only supports single GPU runtime.<br> |
|
-Not compatible with HuggingFace's PEFT.<br> |
