How to run Large Language Model FLAN -T5 and GPT locally

Hello everyone, today we are going to run a Large Language Model (LLM) Google FLAN-T5 locally and GPT2.

When you are building new applications by using LLM and you require a development environment in this tutorial I will explain how to do it.

Introduction

FLAN-T5

FLAN-T5 is a Large Language Model open sourced by Google under the Apache license at the end of 2022. It is available in different sizes - see the model card.

google/flan-t5-small: 80M parameters; 300 MB download
google/flan-t5-base: 250M parameters
google/flan-t5-large: 780M parameters; 1 GB download
google/flan-t5-xl: 3B parameters; 12 GB download
google/flan-t5-xxl: 11B parameters

FLAN-T5 models use the following models and techniques:

The pretrained model T5 (Text-to-Text Transfer Transformer)
The FLAN (Finetuning Language Models) collection to do fine-tuning multiple tasks

GPTNeo

The GPTNeo model was released in the EleutherAI/gpt-neo repository by Sid Black, Stella Biderman, Leo Gao, Phil Wang and Connor Leahy. It is a GPT2 like causal language model trained on the Pile dataset.

Step 1. Installation of Conda

First you need to install anaconda at this link

in this location C:\Anaconda3 , then you, check that your terminal , recognize conda

C:\conda --version
conda 23.1.0

Step 2. Environment creation

The environments supported that I will consider is Python 3.10,

I will create an environment called analysis, but you can put the name that you like.

conda create -n LLM python==3.10

then we activate

conda activate LLM

then in your terminal type the following commands:

python -m pip install --upgrade pip

conda install ipykernel notebook

then

python -m ipykernel install --user --name LLM --display-name "Python (LLM)"

then we can install jupyter lab

pip install jupyterlab

then we install the following libraries used to the creation of our environment

For this

pip install transformers
pip install transformers[torch]

If we have CUDA capability we are going to use CUDA 11.4 and you can download here

pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113

otherwise

pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cpu
conda install pytorch torchvision torchaudio cpuonly -c pytorch

pip install chardet
pip install fitz
pip install PyMuPDF
conda install -c conda-forge ipywidgets
jupyter nbextension enable --py widgetsnbextension

If you have different versions of CUDA you can install the best version of torch that fit your computer here

we would like to create a folder to work

mkdir workspace && cd workspace

later we open a the jupyter lab

jupyter lab

then you create a new notebook Python (LLM)

Google FLAN-T5

There are different models of FLAN-T5 out there. Let us check here two models

google/flan-t5-small
google/flan-t5-large

Large Language Model FLAN-T5 and GTP locally

In this notebook we are going to run different versions of FLAN-T5 and GTP

We define the following prompt:

prompt ="A step by step recipe to make bolognese pasta:"

FLAN-T5-small

Here we are going to download 300 MB of data of the model

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
model = AutoModelForSeq2SeqLM.from_pretrained("google/flan-t5-small")
tokenizer = AutoTokenizer.from_pretrained("google/flan-t5-small")
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))

['Pour a cup of bolognese into a large bowl and add the pasta']

FLAN-T5-large

Here we are going to download 3GB MB of data of the model

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
model = AutoModelForSeq2SeqLM.from_pretrained("google/flan-t5-large")
tokenizer = AutoTokenizer.from_pretrained("google/flan-t5-large")
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))

['Toss the pasta with the sauce, then add the meat and toss again.']

CUDA Capability

import torch
is_cuda=torch.cuda.is_available()
if is_cuda:
    print("This computer uses CUDA") 
else:  
    print("This computer uses CPU")

This computer uses CUDA

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
tokenizer = AutoTokenizer.from_pretrained("google/flan-t5-large")
model = AutoModelForSeq2SeqLM.from_pretrained("google/flan-t5-large").to(device)

inputs = tokenizer(prompt, return_tensors="pt").to(device)

outputs = model.generate(**inputs)
print(tokenizer.batch_decode(outputs, skip_special_tokens=True))

['Toss the pasta with the sauce, then add the meat and toss again.']

GPT-neo-125M

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer, AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("EleutherAI/gpt-neo-125M")
model.to(device)
tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-125M")
input_ids = tokenizer(prompt, return_tensors="pt").to(device)

#outputs = model.generate(**input_ids)
outputs = model.generate(**input_ids, do_sample=True, max_length=400)

Setting `pad_token_id` to `eos_token_id`:50256 for open-end generation.

generation =tokenizer.batch_decode(outputs, skip_special_tokens=False)

print('\n'.join(generation))

A step by step recipe to make bolognese pasta:
Formalizing the ingredients and sauces
Wipe up the ingredients
Wipe the sauce without over or overstitching the ingredients.

FRENCH TENDER

I make a bolognese pasta for a wedding reception, using what I have learned from many other things but one thing about bolognese pasta is that I want a traditional Italian recipe for a wedding. This recipe has an Italian twist:

1/4 ounce Italian sausage cheese
1/4 ounce Italian sausage salt
2/3 ounce Italian sausage fresh ramekins
1/2 ounce Italian sausage chopped onions
1/2 ounce Italian sausage chopped parsley

In a shallow saucepan, melt butter and sauté onion
2/3 ounce Italian sausage with and sauce
salt and pepper
2/3 ounce Italian sausage chopped parsley

Thoroughly sauté onion until it softens
2/3 ounce Italian sausage with and sauce
salt and pepper

Preheat the oven to 325 degrees

Bring a large kettle to 50 to 60°

Sauté onion over medium-high heat
2/3 ounce Italian sausage with and sauce
salt and pepper

In a skillet lightly butter a small pot with 2/3 ounce Italian sauce
salt and pepper

Add 2/3 ounce Italian sauce seasoned with salt, pepper and mix well.
Sift together sausage, seasoning and garlic
Add enough water to bring to boil

Slowly pour in ingredients while stirring
Add enough water to bring to boil

Gravfry the pasta to lightly coat with oil
Place the pasta on the bottom rack with foil

Heat oil in skillet
Oil a small stovetop dish with hot brown sugar
Smoke the sauce. Place your fingers into the meat
sauté onion over hot oven(s)/heat
