Installation & Usage

To use this LoRA fine-tuned model, install the necessary dependencies:

pip install torch torchvision torchaudio
pip install accelerate
pip install transformers
pip install peft
pip install bitsandbytes

Running the Model

Load and merge the LoRA adapter with the base model:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

device = "cuda" if torch.cuda.is_available() else "cpu"
base_model_path = "ibm-granite/granite-3.1-8b-instruct"
lora_model_path = "ruslanmv/granite-3.1-8b-Reasoning-LORA"

tokenizer = AutoTokenizer.from_pretrained(base_model_path)
model = AutoModelForCausalLM.from_pretrained(base_model_path, device_map="auto")

# Load LoRA adapter
model = PeftModel.from_pretrained(model, lora_model_path)
model.eval()

input_text = "Can you explain the difference between inductive and deductive reasoning?"
input_tokens = tokenizer(input_text, return_tensors="pt").to(device)

output = model.generate(**input_tokens, max_length=4000)
output_text = tokenizer.batch_decode(output)

print(output_text)
