Other RL libraries

As we discussed earlier, there are several RL-specific libraries available. Overall, TensorFlow is more popular than PyTorch, as it is more widespread in the deep learning community. The following is my (very biased) list of libraries:

Keras-RL: started by Matthias Plappert in 2016, this includes basic deep RL methods. As suggested by the name, this library was implemented using Keras, which is a higher-level wrapper around TensorFlow (https://github.com/keras-rl/keras-rl).
Dopamine: a library from Google published in 2018. It is TensorFlow-specific, which is not surprising for a library from Google (https://github.com/google/dopamine).
Ray: a library for distributed execution of machine learning code. It includes RL utilities as part of the library (https://github.com/ray-project/ray).
TF-Agents: another library from Google published in 2018 (https://github.com/tensorflow/agents).
ReAgent: a library from Facebook Research. It uses PyTorch...
