Self Imitation Learning @emrul has implemented SAIL, see https://github.com/Stable-Baselines-Team/stable-baselines3-contrib/pull/139#issuecomment-1445114579

@emrul, is there an official implementation for those two? Do you match the results from the paper with your implementation?

[emrul]

Hi @qgallouedec - I haven't don't much testing but if there's no rush I'd love to work on this in my spare time. The official implementation appears to be here: https://github.com/google-research/google-research/tree/master/sail_rl

[qgallouedec]

There is no rush at all :)

Hey everyone,

I have tried the code what @emrul pasted in the IQN PR comments, it works.

One thing what I haven't got to work is the SubProcEenv wrapping. Just wanted to let you know. :)

[emrul]

Thanks @richardjozsa - that's interesting because I exclusively use SubProcVecEnv for training and the Dummy vec env for evaluation. What happens when you use SubProcVecEnv?

[richardjozsa]

This is the error what I got, but if it works for you than I recheck. I use a customenv maybe that caused something.

... looks like an error trying to load your env from Pickle but in my modifications I don't make any changes to envs (the replay buffer holds the SAIL returns internally) so I don't think this should be caused by amendments.

My bad sorry, it was in my environment, it works fine. Only comment, you have set the replay buffer to device= cpu. I guess that can be auto. :)

Great, and yes - good catch on the device, I will correct that!
