## RLeXplore: Accelerating Research in Intrinsically-Motivated Reinforcement Learning

RLeXplore is a unified, highly-modularized and plug-and-play toolkit that currently provides high-quality and reliable implementations of eight representative intrinsic reward algorithms. It used to be challenging to compare intrinsic reward algorithms due to various confounding factors, including distinct implementations, optimization strategies, and evaluation methodologies. Therefore, RLeXplore is designed to provide unified and standardized procedures for constructing, computing, and optimizing intrinsic reward modules.

The workflow of RLeXplore is illustrated as follows:

Installation

• with pip recommended

Open a terminal and install rllte with pip:

conda create -n rllte python=3.8
pip install rllte-core 

• with git

Open a terminal and clone the repository from GitHub with git:

git clone https://github.com/RLE-Foundation/rllte.git
pip install -e .

Now you can invoke the intrinsic reward module by:

from rllte.xplore.reward import ICM, RIDE, ...
