Aviary
The aviary contains:
-
roost,wren,cgcnn.
The aim is to contain multiple models for materials discovery under a common interface
Environment Setup
To use aviary you need to create an environment with the correct dependencies. The easiest way to get up and running is to use anaconda. A cudatoolkit=11.1 environment file is provided environment-gpu-cu111.yml allowing a working environment to be created with:
conda env create -f environment-gpu-cu111.yml
If you are not using cudatoolkit=11.1 or do not have access to a GPU this setup will not work for you. If so please check the following pages PyTorch, PyTorch-Scatter for how to install the core packages and then install the remaining requirements as detailed in requirements.txt.
The code was developed and tested on Linux Mint 19.1 Tessa. The code should work with other Operating Systems but it has not been tested for such use.
Aviary Setup
Once you have set up an environment with the correct dependencies you can install aviary using the following commands from the top of the directory:
conda activate aviary
python setup.py sdist
pip install -e .
This will install the library in an editable state allowing for advanced users to make changes as desired.
Example Use
To test the input files generation and cleaning/canonicalization please run:
python examples/inputs/poscar2df.py
This script will load and parse a subset of raw POSCAR files from the TAATA dataset and produce the datasets/examples/examples.csv file used for the next example. The raw files have been selected to ensure that the subset contains all the correct endpoints for the 5 elemental species in the Hf-N-Ti-Zr-Zn chemical system. All the models used share can be run on the input file produced by this example code. To test each of the three models provided please run:
python examples/roost-example.py --train --evaluate --data-path examples/inputs/examples.csv --targets E_f --tasks regression --losses L1 --robust --epoch 10
python examples/wren-example.py --train --evaluate --data-path examples/inputs/examples.csv --targets E_f --tasks regression --losses L1 --robust --epoch 10
python examples/cgcnn-example.py --train --evaluate --data-path examples/inputs/examples.csv --targets E_f --tasks regression --losses L1 --robust --epoch 10
Please note that for speed/demonstration purposes this example runs on only ~68 materials for 10 epochs - running all these examples should take < 30s. These examples do not have sufficient data or training to make accurate predictions, however, the same scripts have been used for all experiments conducted.

Disclaimer
This research code is provided as-is. We have checked for potential bugs and believe that the code is being shared in a bug-free state. As this is an archive version we will not be able to amend the code to fix bugs/edge-cases found at a later date. However, this code will likely continue to be developed at the location described in the metadata.
