Hi- I still don't understand how to solve this problem. I saw that you encountered the same question as me. It‘s:

The problem, as it seems, is with empty feasible_actions, which, if I understood the code well, should be set by the very publisher on ~safe_actions topic using cbNNActions callback:

def cbNNActions(self, msg):
self.feasible_actions = msg

Since it is empty, calling cbComputeActionGA3C fails with Invalid Feasible Actions message.

Could you tell me how to solve it in details? I can't find no_feasible_action branch. I will appreciate you very much if you could give me some guidance.

Thanks,
Zhang di
