• I have marked all applicable categories:
  • exception-raising bug
  • RL algorithm bug
  • documentation request (i.e. "X is missing from the documentation.")
  • new feature request
• I have visited the source website, and in particular read the known issues
• I have searched through the issue tracker for duplicates
• I have mentioned version numbers, operating system and environment, where applicable:

  import tianshou, sys
  print(tianshou.__version__, sys.version, sys.platform)

Are you thinking about including model-based algorithms in this framwork in the future, e.g., PILCO?
If not, I wonder Is it easy to implement model-based algorithms with the current code structure.
