Usage

To use this LoRA adapter, you need to:

1. Install required packages:

pip install transformers peft torch

2. Load the model with LoRA adapter:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = "meta-llama/Meta-Llama-3-8B"
model = AutoModelForCausalLM.from_pretrained(
    base_model,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(base_model)

# Load LoRA adapter
model = PeftModel.from_pretrained(model, "bootscoder/Llama-3-Medical-8B-SFT-LoRA")

# Generate text
inputs = tokenizer("What is diabetes?", return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

3. Or merge LoRA with base model:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model = "meta-llama/Meta-Llama-3-8B"
model = AutoModelForCausalLM.from_pretrained(base_model, torch_dtype="auto")
model = PeftModel.from_pretrained(model, "bootscoder/Llama-3-Medical-8B-SFT-LoRA")

# Merge and save
merged_model = model.merge_and_unload()
merged_model.save_pretrained("./merged_model")
