Cost-Aware

About Cost-Aware.py

The file Cost-Aware.py implements DQN algorithm manually. The only thing you need to do with this file is to understand the DQN algorithm and how it works.

Use the following command to run the file:

python Cost-Aware.py

This repository will use the standardized DRL libraries Gymnasium and Tianshou to implement the environment and agent training.

Python Environment Setup

Create a new conda environment:

# Create a new conda environment
conda create -n tianshou python=3.11

# Activate the environment
conda activate tianshou

Install Tianshou:

git clone --branch v1.1.0 --depth 1 https://github.com/thu-ml/tianshou.git
cd tianshou
pip install poetry

# Change the source of poetry if necessary
poetry source add --priority=primary tsinghua https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple

poetry lock --no-update
poetry install

Install other dependencies:

pip install -r requirements.txt

Getting Started

Train

Use the following command to train the agent:

python run.py

Use the following command to see adjustable parameters:

python run.py -h

The VM configuration is defined in ./config/vm.yaml.

The best model will be saved in ./logs/{timestamp}-train/best.pth.

Use TensorBoard

tensorboard --logdir ./logs

Evaluate

Use the following command to evaluate the agent:

python run.py --eval --model-path ./logs/{timestamp}-train/best.pth

--eval-episode is used to specify the number of episodes to evaluate the agent.

Use the following command to compare the agent with the baseline and perform significance analysis of the difference:

python run.py --eval --model-path ./logs/{timestamp}-train/best.pth --baseline --eval-episode 50

Use the following command to plot figures:

python run.py --eval --model-path ./logs/{timestamp}-train/best.pth --baseline --eval-episode 50 --plot
