PPO with multi-head/autoregressive action outputs
Hey,
Thanks for your work.
There is one point I am not quite sure. Since the action probs for all the heads except for the first catgorical one are masked out, should we also mask out the corresponding entropy?
When I use stable_baselines3
1.6.2 to run the sample command in README.md
, the program does not run and the error message indicates:
Traceback (most recent call last):
File "main.py", line 164, in
main()
File "main.py", line 36, in main
envs = make_vec_envs(args.env_name, args.seed, args.num_processes,
File "/home/cenyu/multi_action_head_PPO/core/envs.py", line 75, in make_vec_envs
envs = SubprocVecEnv(envs)
TypeError: Can't instantiate abstract class SubprocVecEnv with abstract methods env_is_wrapped
Once I implemented the corresponding abstract method env_is_wrapped
in the SubprocVecEnv
class in subproc_vec_env.py
, the sample works fine
