Google Colab Interface Demo (easy)

For ease of use without any hardware requirements, a Google Colab interface is available here: tiny.cc/catpred. It contains sample data, instructions and installation all in the Colab notebook.

Local Demo

If you would like to install the package on a local machine, please follow the following instructions.

System Requirements

For using pre-trained models to predict, any machine running a Linux based operating system is recommended. For training, we recommend using a Linux based operating system on a GPU-enabled machine.

Both training and prediction have been tested on Ubuntu 20.04.5 LTS with NVIDIA A10 and CUDA Version: 12.0

To train with GPUs, you will need:

• cuda >= 11.7
• cuDNN

Installation

Both options require conda, so first install Miniconda from https://conda.io/miniconda.html.

Then proceed to either option below to complete the installation. If installing the environment with conda seems to be taking too long, you can also try running conda install -c conda-forge mamba and then replacing conda with mamba in each of the steps below.

Note for machines with GPUs: You may need to manually install a GPU-enabled version of PyTorch by following the instructions here. If you're encountering issues with not using a GPU on your system after following the instructions below, check which version of PyTorch you have installed in your environment using conda list | grep torch or similar. If the PyTorch line includes cpu, please uninstall it using conda remove pytorch and reinstall a GPU-enabled version using the instructions at the link above.

Installing and downloading pre-trained models (~5 mins)

1. git clone https://github.com/maranasgroup/catpred.git
2. cd CatPred
3. conda env create -f environment.yml
4. conda activate catpred
5. pip install -e .
6. pip install ipdb fair-esm rotary_embedding_torch==0.6.5 egnn_pytorch -q
7. wget https://catpred.s3.amazonaws.com/production_models.tar.gz -q
8. wget https://catpred.s3.amazonaws.com/processed_databases.tar.gz -q
9. tar -xzf production_models.tar.gz
10. tar -xzf processed_databases.tar.gz

Run a demo (~2 mins)

Use the demo.ipynb jupyter notebook to run the demo.

Reproducing publication training/results

In order to train publication models, you must download and extract training datasets using

wget https://https://catpred.s3.amazonaws.com/publication_training_datasets.tar.gz -q
tar -xzf publication_training_datasets.tar.gz

Training

TODO: Will be made available upon publication
