Project Templete to Kickoff Machine Learning Project

This template currently uses Python 3.11, and either conda, docker, poetry, or micromamba

Template project aims to promote versioning library, environment isolation practice and help all ML practitioners quickly start a project. Using this template, practitioners will have below libraries

  • Pytorch
  • Torch-geometric
  • Transfomer
  • Pytorch-Lightning
  • Wandb
  • Pandas
  • Numpy
  • Scikit-Learn
  • Jupyter Notebook
  • Panel
  • Pytest
  • DVC

Those libraries of course aren't enough, but it's easy to update other libraries that support your project.

Using poetry is highly recommended. If you are using conda or micromamba, make sure that you use package hashes to ensure package selection is reproducible via conda-lock or micromamba

Install library dependencies

With poetry

  • pip install poetry
  • Create, install, activate environment
poetry install --with cpu # cpu
poetry install --with cu117 # cuda 11.7
poetry shell
  • Need to update environment after poetry add a_lib
poetry lock

Note: in case you have a problem, run

export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring
  • Need to add source, e.g pyg-cu117
poetry source add pyg-cu117 https://data.pyg.org/whl/torch-2.0.0+cu117.html

supposing add pyg_lib, torch_scatter, ... to a group (cu117) in this project via the source

poetry add -G cu117 pyg_lib torch_scatter torch_sparse torch_cluster torch_spline_conv --source pyg-cu117

With conda

  • Install Conda instruction: conda.io
  • Create, install, activate environment
conda env create -f environment.yml
conda activate ml-venv
  • Need to update environment
conda env update --file binder/environment.yml --prune
  • Export environment
conda env export --from-history -f binder/environment.yml

With docker

  • This tutorial is for those who have NVIDIA GPU (hereafter GPU). For CPU case, this should be similar but need to adjust Dockerfile and run_docker.sh
  • Note: Docker will use micromamba instead of miniconda. Replace conda with micromamba in your usual commands
  • You need to install docker
  • Install Nvidia driver (ignore if you don't have GPU)
  • Then install Nvidia docker container toolkit, ignore if you aim to use CPU.
  • Edit .env locates the same level with run_docker.sh, to add environment variables to the prospective docker container
  • There is a file named run_docker.sh, allow to execute it by chmod +x run_docker.sh and run run_docker.sh
  • Enjoy Jupyter lab at localhost:8888 as usual. Notebook token is shown after run_docker.sh runs successfully

After installing libraries, verify

try this in ipython

import torch
from torch_geometric.data import Data

edge_index = torch.tensor([[0, 1],
                           [1, 0],
                           [1, 2],
                           [2, 1]], dtype=torch.long)
x = torch.tensor([[-1], [0], [1]], dtype=torch.float)

data = Data(x=x, edge_index=edge_index.t().contiguous())

Q&A

My default Python is not 3.11, how I can instruct poetry to use Python 3.11

Use poetry env use to select Python version, more details are at more details https://stackoverflow.com/questions/60580113/change-python-version-to-3-x

I don't want to use Python 3.11, how to change configs and make it reproducible

If you aim to use poetry, the steps are following

  • edit file pyproject.toml
  • select a Python version, then poetry shell
  • generate new poetry.lock by run poetry lock

If you aim to follow conda

  • edit file environment.yml
  • create a new environment that has the version you want
  • switch to that environment
