Code for the paper https://arxiv.org/abs/2308.10364. Results can be obtained by running the commands in the Experiments section.
JAX needs to be installed independently following the instruction on the JAX homepage. At time of publishing we used JAX 0.4.13 with python 3.10. This repo also has dependency on pytorch (NB: use CPU version so it doesn't clash with JAX) which may be installed with:
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
For the alanine dipeptide problem we need to install openmmtools with conda:
conda install -c conda-forge openmm openmmtools
Finally then,
pip install -e .
Experiments may be run with the following commands.
We use hydra to configure all experiments.
The flow type may be set as shown in the first line.
For Alanine Dipeptide the data must first be downloaded from Zenodo which may be
done with the script eacf/targets/aldp.sh.
For running an experiment make sure to configure the WANDB logger in the config file to match your WANDB account (e.g. for dw4 see experiments/config/dw4.yaml ).
python examples/dw4.py flow.type=spherical # Flow types: spherical,proj,along_vector,non_equivariant
python examples/lj13.py
python examples/qm9.py
python examples/aldp.py
python examples/dw4_fab.py
python examples/lj13_fab.pyThe code for the equivariant CNF baseline can be found in the ecnf-baseline-neurips-2023 repo.
