Potential Energy Surface Network (PESNet)

Reference implementation of PESNet from

and Planet and PESNet++ from

Generalizing Neural Wave Functions

If you're looking for the code of our ICML paper, please check out our globe repository.

Run the code

First install JAX and the correct CUDA Toolkit and CUDNN, then this package via

pip install -e .

You can now train a model, e.g., H2, via a config file

python train.py with configs/systems/h2.yaml print_progress=True

You can overwrite parameters either via CLI or via the config file. All progress is tracked on tensorboard.

Reproduce the experiments

We encourage the use of seml to manage all experiments but we also supply commands to run the experiments directly.

PESNet++ ablation study on N2

With seml:

seml n2_ablation add train_n2_ablation.yaml start

Without seml:

# PESNet
python train.py with configs/systems/n2.yaml \\
    init_method=pesnet \\
    pesnet.ferminet_params.activation=tanh \\
    pesnet.ferminet_params.input_config.mlp_activation=tanh \\
    pesnet.ferminet_params.jastrow_config=None \\
    pesnet.ferminet_params.determinants=32
# PESNet++ (default config)
python train.py with configs/systems/n2.yaml \\
    init_method=pesnet \\
    pesnet.ferminet_params.activation=silu \\
    pesnet.ferminet_params.input_config.mlp_activation=silu \\
    pesnet.ferminet_params.jastrow_config.n_layers=3 \\
    pesnet.ferminet_params.jastrow_config.activation=silu \\
    pesnet.ferminet_params.determinants=32

Potential Energy Surfaces

To run all experiments from the PlaNet paper with seml simply run:

seml pes add train_pes.yaml start
