What is Ray in the context of reinforcement learning?

Ray, in the context of reinforcement learning, is an open-source Python library specifically designed for building and running distributed applications. It provides a unified framework for executing parallel and distributed workloads, which is particularly beneficial for reinforcement learning tasks that often require extensive computational resources. The library allows for the seamless scaling of training algorithms across multiple nodes, enabling researchers and practitioners to efficiently manage many agents and simulations concurrently.

Ray simplifies the complexity of distributed computing by offering an easy-to-use API that supports the development and execution of reinforcement learning algorithms. It features components such as Ray RLib that are tailored for reinforcement learning, making it more straightforward to implement state-of-the-art methods in a distributed manner.

By focusing on efficiency and simplicity, Ray empowers developers to experiment with complex models, handle large datasets, and leverage computational resources effectively. This makes it a prominent choice among professionals working in the field of reinforcement learning.
