Adjustments needed to make for running my task

Hi,

Before I start, this code was largely ported from Python under the desire of minimal effort, so don't assume certain parts were well-thought-through and feel free to change anything you like.

1,2) Yeah that should be it.

a1) Eval() should be fine to get action, but perhaps look into playback() of ppo.cpp for inspiration on how I used it in conjunction with stepping through the environment. As far as I remember, playback() is called when you ask for inference from CLI (as I think I described in the readme.MD, perhaps worth reading that part).

a2) Generally, PPO outputs stochastic actions, but I chose to use only means during inference. You can change it if you like, not sure what are your needs. I am sure there is a stochastic counterpart in the graph at least.

a3) As for value and step look at the fetches. Step gets you action and stuff, and value gets you value. But you are right in that they are confusing. Again, mindless porting.

b) If you use the latest StableBaselines you are likely to get in trouble, as I never updated my stuff. What I would recommend is to use a modified version which I host and refer to in Singularity files. I think there is also explicit repository listing in the readme.md.

Hope this helps, Good luck!
