How to Get Started with the Model

Installation

pip install -qU  transformers==4.36.2  datasets python-dotenv peft bitsandbytes accelerate 

Use the code below to get started with the model.

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline, logging, BitsAndBytesConfig
import os, torch

# Define the name of your fine-tuned model
finetuned_model = 'ruslanmv/Medical-Mixtral-7B-v1.5k'

# Load fine-tuned model
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16,
    bnb_4bit_use_double_quant=False,
)
model_pretrained = AutoModelForCausalLM.from_pretrained(
    finetuned_model,
    load_in_4bit=True,
    quantization_config=bnb_config,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(finetuned_model, trust_remote_code=True)

# Set pad_token_id to eos_token_id
model_pretrained.config.pad_token_id = tokenizer.eos_token_id

pipe = pipeline(task="text-generation", model=model_pretrained, tokenizer=tokenizer, max_length=100)

def build_prompt(question):
  prompt=f"[INST]@Enlighten. {question} [/INST]"
  return prompt

question = "What does abutment of the nerve root mean?"
prompt = build_prompt(question)

# Generate text based on the prompt
result = pipe(prompt)[0]
generated_text = result['generated_text']

# Remove the prompt from the generated text
generated_text = generated_text.replace(prompt, "", 1).strip()

print(generated_text)
