  • Classification (binary or multi-class)
  • Regression
  • Multi-task learning
  • Generative model building
• Data Types:
  • SMILES strings or amino-acid sequences
  • Molecular graphs (conversion from SMILES is handled by OpenChem)

Installing OpenChem

To harness the capabilities of OpenChem, follow the installation steps below.

Requirements

Before diving into the installation process, ensure that you have:

• A modern NVIDIA GPU with compute capability 3.5 or newer.
• Python version 3.5 or newer (we recommend using Anaconda distribution).
• CUDA version 9.0 or newer.

General Installation Steps

For those using Anaconda Python, follow these commands to install OpenChem:

git clone https://github.com/Mariewelt/OpenChem.git
cd OpenChem
conda create --name OpenChem python=3.7
conda activate OpenChem
conda install --yes --file requirements.txt
conda install -c rdkit rdkit nox cairo
conda install pytorch torchvision -c pytorch
pip install -e .

If your CUDA version is older than 9.0, make sure to check the PyTorch website for the appropriate installation instructions.

Installation with Docker

If you prefer, you can opt for a Docker-based installation. A Dockerfile is provided so that you can run your models in a pre-configured container with all necessary packages readily installed. Note that you will also need to have nvidia-docker to utilize GPU capabilities.

Troubleshooting Tips

As with any programming tool, you may encounter some hiccups during installation or usage. Here are a few troubleshooting ideas:

• Issues with TensorBoard not launching? Ensure you have installed the required dependencies.
• If you encounter problems during model training, double-check that your GPU meets all specifications and is correctly configured.
• For any other issues, reach out to the community or refer to the comprehensive OpenChem documentation.
• For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
