doodad

A library for launching python programs on different machines. Currently supports running locally and over EC2 and SSH (via Docker) with minimal (if any) modification to your existing program.

EC2 code is based on rllab's code.

Setup

• Add this repo to your pythonpath.

export PYTHONPATH=$PYTHONPATH:/path/to/this/repo

• Install dependencies

pip install -r requirements.txt

• (Optional) Set up EC2

python scripts/ec2_setup.py

• (Optional) Set up Docker. This is required on the target machine if running in a Docker-enabled mode.

• (Optional) Set up GCP

Example

See ec2_launch_test.py for an example on how to run scripts on EC2, over SSH, or locally.

Changelog

17 March 2020 (v0.2.4)

• Add doodad.easy_launch to make it very easy to run python functions across different modes supported by doodad.

04 March 2020 (v0.2.3)

• SlurmConfig is only responsible for config.
• Require user to explicitly specify whether or not they want to overwrite generated script in ScriptSlurmSingularity and BrcHighThroughputMode

26 February 2020 (v0.2.2)

• Refactor slurm-based modes.
• Add support for Berkeley Research Compute's high-throughput node.

TODOs

• Add support for automatic experiment restarting (will require the user to write a save_state and restore_state function, or use something like CRIU)
• Fix output directories when using docker showing up as root permissions.

doodad.easy_launch

The doodad.easy_launch module is intended to make it very easy to launch experiments. Usage:

from doodad.easy_launch.python_function import run_experiment


def function(doodad_config, variant):
    print("The learning rate is", variant['learning_rate'])
    print("You are", variant['parameter'])
    print("Save to", doodad_config.base_log_dir)
    # save outputs (e.g. logs, parameter snapshots, etc.) to
    # doodad_config.base_log_dir

if __name__ == "__main__":
    variant = dict(
        learning_rate=1e-4,
        parameter='awesome',
    )
    run_experiment(
        function,
        exp_name='ec2-test-doodad-easy-launch',
        mode='ec2',
        variant=variant,
    )

To use it you well need to create a private version of the configuration file:

cp doodad/easy_launch/config.py doodad/easy_launch/config_private.py

See the README for more details.
