Automatic hyperparameter optimizer based on Ax/Botorch

OmniOpt2

A hyperparameter optimizer for SLURM-based systems. GUI for creating commands is available at https://imageseg.scads.de/omniax/ , where also additional help can be found.

Main program

./omniopt --partition=alpha --experiment_name=example --mem_gb=1 --time=60 \
    --worker_timeout=60 --max_eval=500 --num_parallel_jobs=500 --gpus=1 \
    --follow --run_program=ZWNobyAiUkVTVUxUOiAlKHBhcmFtKSI= \
    --parameter param range 0 1000 float

This will automatically install all dependencies. Internally, it calls a python-script.

Show results

./omniopt_evaluate

Plot results

./plot --run_dir runs/example/0

Or, with --min and --max:

./plot --run_dir runs/example/0 --min 0 --max 100

Run tests

Runs the main test suite. Runs an optimization, continues it, tries to continue one that doesn't exit, and runs a job with many different faulty jobs that fail in all sorts of ways (to test how OmniOpt2 reacts to it).
