GenRL is a PyTorch reinforcement learning library centered around reproducible and generalizable algorithm implementations.
Reinforcement learning research is moving faster than ever before. In order to keep up with the growing trend and ensure that RL research remains reproducible, GenRL aims to aid faster paper reproduction and benchmarking by providing the following main features:
- PyTorch-first: Modular, Extensible and Idiomatic Python
- Unified Trainer and Logging class: code reusability and high-level UI
- Ready-made algorithm implementations: ready-made implementations of popular RL algorithms.
- Faster Benchmarking: automated hyperparameter tuning, environment implementations etc.
By integrating these features into GenRL, we aim to eventually support any new algorithm implementation in less than 100 lines.

GenRL is compatible with Python 3.6 or later and also depends on pytorch and openai-gym. The easiest way to install GenRL is with pip, Python's preferred package installer.
$ pip install genrl
Note that GenRL is an active project and routinely publishes new releases. In order to upgrade GenRL to the latest version, use pip as follows.
$ pip install -U genrl
If you intend to install the latest unreleased version of the library (i.e from source), you can simply do:
$ git clone https://github.com/SforAiDl/genrl.git
$ cd genrl
$ python setup.py install
