Libraries

How to use ISTA-DASLab/Llama-2-13b-AQLM-2Bit-1x16-hf with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ISTA-DASLab/Llama-2-13b-AQLM-2Bit-1x16-hf")

# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("ISTA-DASLab/Llama-2-13b-AQLM-2Bit-1x16-hf")
model = AutoModelForMultimodalLM.from_pretrained("ISTA-DASLab/Llama-2-13b-AQLM-2Bit-1x16-hf")
