Ipython / Notebook friendly
Tensorboard support
PEP8 code style adherence
Custom callback functionality
High code coverage
Type hints for better code quality

Use Cases

Researchers and data scientists using reinforcement learning for experiments and model development.
Industry professionals implementing reinforcement learning solutions in production environments.
Educators and students learning about reinforcement learning through practical applications.

Advantages

Provides a common interface for various reinforcement learning algorithms, simplifying experimentation.
Offers extensive documentation and resources for beginners to get started with RL.
Supports a wide range of features, including custom environments, policies, and callbacks, enhancing flexibility.

Limitations / Considerations
