Parallelism Caveats

both the threading and multiprocessing packages are supported by nes-py with some caveats related to rendering:

  1. rendering is not supported from instances of threading.Thread
  2. rendering is supported from instances of multiprocessing.Process, but nes-py must be imported within the process that executes the render call

Development

To design a custom environment using nes-py, introduce new features, or fix a bug, please refer to the Wiki. There you will find instructions for:

  • setting up the development environment
  • designing environments based on the NESEnv class
  • reference material for the NESEnv API
  • documentation for the nes_py.wrappers module
