PTAN stands for PyTorch AgentNet -- reimplementation of AgentNet library for PyTorch
This library was used in "Deep Reinforcement Learning Hands-On" book, here you can find sample sources.
The repository is maintained to keep dependency versions up-to-date. This requires efforts and time to test all the examples on new versions, so, be patient.
The logic is following: there are several branches of the code, corresponding to major pytorch version code was tested. Due to incompatibilities in pytorch and other components, code in the printed book might differ from the code in the repo.
At the moment, there are the following branches available:
master
: contains the code with the latest pytorch which was tested. At the moment, it is pytorch 1.7.torch-1.3-book-ed2
: code printed in the book (second edition) with minor bug fixes. Uses pytorch=1.3 which is available only on conda repos.torch-1.7
: pytorch 1.7. Merged with master.
All the branches uses python 3.7, more recent versions weren't tested.
