Open Principal Odor Map

Replication of the Principal Odor Map paper by Brian K. Lee et al. (2023) [1]. The model is implemented such that it integrates with DeepChem.

Installation (Python 3.9 and above)

PyPI based installation

1. pip install openpom

openpom requires cuda verion of dgl libraries
For cuda 11.7, steps below can be followed:

2. pip install  dgl -f https://data.dgl.ai/wheels/cu117/repo.html

3. pip install  dglgo -f https://data.dgl.ai/wheels-test/repo.html

Note: If you are using Amazon Linux 2 based OS on EC2 instance, use:

pip install  dgl==1.1.2 -f https://data.dgl.ai/wheels/cu117/repo.html

Github fork based installation

1. Fork the OpenPOM repository and clone the forked repository

git clone https://github.com/YOUR-USERNAME/openpom.git
cd openpom

2. Setup conda environment

conda create -n open_pom python=3.9
conda activate open_pom

3. Install openpom

pip install .

or (for developing)

python setup.py develop

4. Install DGL cuda libs

pip install  dgl -f https://data.dgl.ai/wheels/cu117/repo.html

pip install  dglgo -f https://data.dgl.ai/wheels-test/repo.html
