How to Get Started with the Model

Use the code below to get started with the model.

How to run from Python code

First install the package

pip install -q -U bitsandbytes accelerate torch huggingface_hub
pip install -q -U git+https://github.com/huggingface/transformers.git # Install latest version of transformers
pip install -q -U git+https://github.com/huggingface/peft.git
pip install flash-attn --no-build-isolation

Import

import torch
import os
from torch import bfloat16
from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline, BitsAndBytesConfig, LlamaForCausalLM

Use a pipeline as a high-level helper

model_id_mistral = "alokabhishek/Mistral-7B-Instruct-v0.2-bnb-4bit"

tokenizer_mistral = AutoTokenizer.from_pretrained(model_id_mistral, use_fast=True)

model_mistral = AutoModelForCausalLM.from_pretrained(
    model_id_mistral,
    device_map="auto"
)


pipe_mistral = pipeline(model=model_mistral, tokenizer=tokenizer_mistral, task='text-generation')

prompt_mistral = "Tell me a funny joke about Large Language Models meeting a Blackhole in an intergalactic Bar."

output_mistral = pipe_llama(prompt_mistral, max_new_tokens=512)

print(output_mistral[0]["generated_text"])
