lmurg 1.0.1

LLM-Based Neural Network Generator

GPT-Driven Neural Network Generator

_{short alias lmurg}

Overview 📖

This Python-based NNGPT project leverages large language models (LLMs) to automate the creation of neural network architectures, streamlining the design process for machine learning practitioners. It leverages various neural networks from the LEMUR Dataset to fine-tune LLMs and provide insights into potential architectures during the creation of new neural network models.

Create and Activate a Virtual Environment (recommended)

For Linux/Mac:

python3 -m venv .venv
source .venv/bin/activate

For Windows:

python3 -m venv .venv
.venv\Scripts\activate

It is also assumed that CUDA 12.6 is installed. If you have a different version, please replace 'cu126' with the appropriate version number.

Environment for NNGPT Developers

Pip package manager

Prerequisites for mpi4py package:

• On Debian/Ubuntu systems, run:

     sudo apt install libmpich-dev    # for MPICH
  
     sudo apt install libopenmpi-dev  # for Open MPI
  

• On Fedora/RHEL systems, run:

     sudo dnf install mpich-devel     # for MPICH
  
     sudo dnf install openmpi-devel   # for Open MPI
  

Create a virtual environment, activate it, and run the following command to install all the project dependencies:

python -m pip install --upgrade pip
pip install -r requirements.txt --extra-index-url https://download.pytorch.org/whl/cu126
pip install -r requirements-no-isolation.txt --no-build-isolation --extra-index-url https://download.pytorch.org/whl/cu126

If there are installation problems, install the dependencies from the 'requirements.txt' file one by one.

Update of NN Dataset

Remove an old version and install LEMUR Dataset from GitHub to get the most recent code and statistics updates:

rm -rf db
pip uninstall nn-dataset -y
pip install git+https://github.com/ABrain-One/nn-dataset --upgrade --force --extra-index-url https://download.pytorch.org/whl/cu126

Installing the stable version:

pip install nn-dataset --upgrade --extra-index-url https://download.pytorch.org/whl/cu126

Adding functionality to export data to Excel files and generate plots for analyzing neural network performance:

pip install nn-stat --upgrade --extra-index-url https://download.pytorch.org/whl/cu126

and export/generate:

python -m ab.stat.export

Docker

All versions of this project are compatible with AI Linux and can be seamlessly executed within the AI Linux Docker container.

Installing the latest version of the project from GitHub

docker run --rm -u $(id -u):ab -v $(pwd):/a/mm abrainone/ai-linux bash -c "[ -d nn-gpt ] && git -C nn-gpt pull || git -c advice.detachedHead=false clone --depth 1 https://github.com/ABrain-One/nn-gpt"

Running script

docker run --rm -u $(id -u):ab --shm-size=16G -v $(pwd)/nn-gpt:/a/mm abrainone/ai-linux bash -c "python -m ab.gpt.TuneNNGen_8B"

The recently added dependencies might be missing in the AI Linux. In this case, you can create a container from the Docker image abrainone/ai-linux, install the missing packages (preferably using pip install <package name>), and then create a new image from the container using docker commit <container name> <new image name>. You can use this new image locally or push it to the registry for deployment on the computer cluster.

Use

• ab.gpt.NNAlter*.py – Generates modified neural network models.
  Use the -e argument to set the number of epochs for the initial CV model generation.

• ab.gpt.NNEval.py – Evaluates the models generated in the previous step.

• ab.gpt.TuneNNGen*.py – Performs fine-tuning and evaluation of an LLM. For evaluation purposes, the LLM generates neural network models, which are then trained to assess improvements in the LLM’s performance on this task. The -s flag allows skipping model generation for the specified number of epochs.
