EasyRunner is a lightweight tool for managing and executing multiple parallel experiments with minimum dependencies. It simplifies the process of running multiple experiments with different configurations or hyperparameters, while monitoring system resources.

Features

• Run multiple experiments in parallel
• Simple dependencies. It only depends on prettytable and psutil library. So you can basically use this for any platforms.
• Monitor system resources (CPU and memory usage) during experiments
• Early termination of experiments by inputting the experiment number
• Colorized display of experiment status and resource usage
• Generate a list of instructions from a template and arguments

Installation

The simpliest way is to install via PyPI.

pip install easy_runner

Alternatively, you can also install from source, simply download or clone this repository and then:

git clone https://github.com/liuzuxin/easy-runner.git
cd easy-runner
pip install -e .

Usage

1. Initialize an EasyRunner object with the required parameters.
2. Specificy a list of commandline instructions to run.
3. Use the start method to run experiments. You can specify a list of GPU IDs for running experiments (or None by default).
4. Optionally, use the compose method to generate a list of instructions from a template and arguments.

A simple example for running a list of instructions (2 parallel) on cuda 0, 1:

from easy_runner import EasyRunner

# Initialize the EasyRunner
runner = EasyRunner(log_name="experiment_logs")

# Create a list of instructions
instructions = [
    "python script1.py --param1 0.1 --param2 100",
    "python script1.py --param1 0.2 --param2 200",
    "python script2.py --param1 0.3 --param2 300",
    "python script2.py --param1 0.4 --param2 400",
    "python script3.py --param1 0.5 --param2 500"
]

# Run experiments
runner.start(instructions, gpus=[0, 1], max_parallel=2)

Anoter example of how to use the compose feature to perform grid search:

from easy_runner import EasyRunner

# Initialize the EasyRunner
runner = EasyRunner(log_name="experiment_logs")

# List of seeds, and tasks
seeds = [0, 10, 20]
tasks = ["TaskA-v0 --epoch 30", "TaskB-v0 --epoch 150", "TaskC-v0 --epoch 80"]

# Define the command template
template = "nohup python train_script.py --project my_project --seed {} --task {} "

# Generate a list of instructions using the compose method
instructions = runner.compose(template, [agents, seeds, tasks])

# Run the experiments
runner.start(instructions, max_parallel=4)

You can try the example scripts in the examples folder:

cd examples
python test_easy_runner.py
