Hmm, I've mainly used replay_actions to look at stats over many replays. It's quite possible there's a bug in the termination condition for a single replay. It probably also doesn't do what you are expecting it to do. It just outputs which actions are popular. This was mainly useful for figuring out the action space, not for training agents. It should be a good example of how to parse through a large number of replays though. You can then do whatever you want with the observations.

It'd be nice if replay_actions was split between the replay parser and the analysis so it could let you do more than collect stats about actions. It'd be good to have that as one option, but it would be nice for it to be easy to write your own that just took observations and could do whatever it wants with them, but without having to deal with starting up the game, doing the parallelism stuff, etc. This would be analogous to bin/agent.py which lets you pass in an agent of your own.

Hi tewalds,
@tewalds
I am having the same problem as xuhuazhe using replay_actions.py also the scrapper version from cole_maclean as well.

The replay info will show up, but not for the actions:

I am using the newest SC2 version 4.1.3 with a replay produced in the same version.

You mentioned you are only using replay_actions.py to see statistics, If i understand it correctly, this script should allow us to see how many units one player have at a given time? can it?

Thank you for your help!
