How to train JUMP models

1. Train on univariate toy data (example)

# train nbinom
python train_toy.py --config-path ./configs/synthetic/jump/nbinom_jump.json --train --num-runs 5 --num-gpus 1 --verbose

• num-runs: number of experiment runs
• num-gpus: number of GPUs available (used for hyperparameter sweeps)
• train: whether to train or to summarize existing experiment results
• verbose: print progress bar and other training logs

2. Train on image data (example)

# cifar-10 (1 GPU)
python train.py --config-path ./configs/cifar10_ordinal_jump.json --verbose
# cifar-10 (4 GPUs)
torchrun --standalone --nproc_per_node 4 --rdzv_backend c10d train.py --config-path ./configs/cifar10_ordinal_jump.json --distributed-mode elastic --num-gpus 4 --verbose
