I have been using the Stable Baselines Open Source Project for a while now, and I must say it is an excellent tool for reinforcement learning tasks. The extensive documentation on their website stable-baselines.readthedocs.io makes it easy to get started. It has a great variety of pre-implemented algorithms and environments that are very useful. The examples provided are also top-notch, helping to better understand the concepts. The code is well-organized and easy to read. Overall, I highly recommend it for anyone working on RL projects.
