Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "tiiuae/falcon-7b-instruct",
    trust_remote_code=True,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "falcon-7b-custom-dpo-lora-lablebox")

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("falcon-7b-custom-dpo-lora-lablebox")

# Generate text
prompt = "What is machine learning?"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=100)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
