GRID

Install

pip install git+https://github.com/mariogeiger/grid

or in local

python setup.py install

Usage

Save results

The file example.py is a minimal script that can be used with grid.

python -m grid results "python example.py" --a 1 2 3 --b 5 6 7

All the combination of (1, 2, 3) and (5, 6, 7) are executed in simultaneously

Example: using slurm and only varying parameter b

python -m grid results "srun --partition gpu --qos gpu --gres gpu:1 --time 3-00:00:00 --mem 12G --pty python example.py --a 4" --b:int 5 6 7

Load results

from grid import load

runs = load('./results/')
print('{} results loaded'.format(len(runs)))

Load in groups

from grid import load_grouped
import matplotlib.pyplot as plt

args, groups = load_grouped('./results/', ['b'])

for param, rs in groups:
    rs = sorted(rs, key=lambda r: r['args'].b)
    label = "a={0[a]}".format(param)
    plt.plot([r['args'].b for r in rs], [r['division'] for r in rs], label=label)

Optional arguments

--n N maximum number of job running in the same time

--sleep S time to sleep in seconds between two job launch

Subcommands

  • pyhton -m grid.clean log_dir remove files with no content (typically resultant of interrupted runs)
  • pyhton -m grid.merge log_dir_src log_dir_dst
  • pyhton -m grid.info log_dir
