XuanPolicy: A Comprehensive and Unified Deep Reinforcement Learning Library

XuanPolicy is an open-source ensemble of Deep Reinforcement Learning (DRL) algorithm implementations.

We call it as Xuan-Ce (玄策) in Chinese. "Xuan (玄)" means incredible and magic box, "Ce (策)" means policy.

DRL algorithms are sensitive to hyper-parameters tuning, varying in performance with different tricks, and suffering from unstable training processes, therefore, sometimes DRL algorithms seems elusive and "Xuan". This project gives a thorough, high-quality and easy-to-understand implementation of DRL algorithms, and hope this implementation can give a hint on the magics of reinforcement learning.

We expect it to be compatible with multiple deep learning toolboxes( PyTorch, TensorFlow, and MindSpore), and hope it can really become a zoo full of DRL algorithms.

Installation

The library can be run at Linux, Windows, MacOS, and EulerOS, etc.

Before installing XuanPolicy, you should install Anaconda to prepare a python environment.

After that, open a terminal and install XuanPolicy by the following steps.

Step 1: Create a new conda environment (python>=3.7 is suggested):

conda create -n xpolicy python=3.7

Step 2: Activate conda environment:

conda activate xpolicy

Step 3: Install the library:

pip install xuanpolicy

This command does not include the dependencies of deep learning toolboxes. To install the XuanPolicy with deep learning tools, you can type pip install xuanpolicy[torch] for PyTorch, pip install xuanpolicy[tensorflow] for TensorFlow2, pip install xuanpolicy[mindspore] for MindSpore, and pip install xuanpolicy[all] for all dependencies.

Note: Some extra packages should be installed manually for further usage.

Basic Usage

Quickly Start

Train a Model

import xuanpolicy as xp

runner = xp.get_runner(agent_name='dqn', env_name='toy/CartPole-v0', is_test=False)
runner.run()

Test the Model

import xuanpolicy as xp

runner_test = xp.get_runner(agent_name='dqn', env_name='toy/CartPole-v0', is_test=True)
runner_test.run()

Logger

You can use tensorboard to visualize what happened in the training process. After training, the log file will be automatically generated in the directory ".results/" and you should be able to see some training data after running the command.

$ tensorboard --logdir ./logs/dqn/torch/CartPole-v0

If everything going well, you should get a similar display like below.
