Usage

from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
import torch

# Configure 4-bit quantization
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16,
    bnb_4bit_use_double_quant=True
)

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("alfaxadeyembe/gemma2-27b-swahili-it")
model = AutoModelForCausalLM.from_pretrained(
    "alfaxadeyembe/gemma2-27b-swahili-it",
    quantization_config=bnb_config,
    device_map="auto",
    torch_dtype=torch.bfloat16
)

# Always set to eval mode for inference
model.eval()

# Example usage
prompt = "Eleza dhana ya uchumi wa kidijitali na umuhimu wake katika ulimwengu wa leo."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model.generate(
