TopoModelX (TMX) is a Python module for topological deep learning. It offers simple and efficient tools to implement topological neural networks for science and engineering.

TMX's development follows the topological deep learning (TDL) blue print laid out in:

• Hajij et al. 2023. Topological Deep Learning: Going Beyond Graph Data.

TMX can reproduce and extend the topological neural networks (TNNs) surveyed in:

• Papillon et al. 2023. Architectures of Topological Deep Learning: A Survey on Topological Neural Networks.

See our graphical literature review with message-passing equations available at https://github.com/awesome-tnns/awesome-tnns.

Note: TMX is still under development.

To develop tmx on your machine, here are some tips.

First, we recommend using Python 3.11.3, which is the python version used to run the unit-tests.

For example, create a conda environment:

conda create -n tmx python=3.11.3
conda activate tmx

Then:

1. Clone a copy of tmx from source:

   git clone [email protected]:pyt-team/TopoModelX.git
   cd TopoModelX

2. Install tmx in editable mode:

   pip install -e '.[all]'

   Notes:

   • Requires pip >= 21.3. Refer: PEP 660.
   • On Windows, use pip install -e .[all] instead (without quotes around [all]).

3. Install torch, torch-scatter, torch-sparse with or without CUDA depending on your needs.

   pip install torch==2.0.1 --extra-index-url https://download.pytorch.org/whl/${CUDA}
   pip install torch-scatter torch-sparse -f https://data.pyg.org/whl/torch-2.0.1+${CUDA}.html
   pip install torch-cluster -f https://data.pyg.org/whl/torch-2.0.0+${CUDA}.html

   where ${CUDA} should be replaced by either cpu, cu102, cu113, or cu115 depending on your PyTorch installation (torch.version.cuda).

4. Ensure that you have a working tmx installation by running the entire test suite with

   pytest

   In case an error occurs, please first check if all sub-packages (torch-scatter, torch-sparse, torch-cluster and torch-spline-conv) are on its latest reported version.

5. Install pre-commit hooks:

   pre-commit install
