CLI tool

Optilab comes with a powerful CLI tool to easily summarize your experiments. It allows for plotting the results and performing statistical testing to check for statistical significance in optimization results.

Optilab CLI utility.
usage: python -m optilab [-h] [--hide_plots] [--test_y] [--test_evals] pickle_path

positional arguments:
  pickle_path   Path to pickle file or directory with optimization runs.

options:
  -h, --help    show this help message and exit
  --hide_plots  Hide plots when running the script.
  --test_y      Perform Mann-Whitney U test on y values.
  --test_evals  Perform Mann-Whitney U test on eval values.
