TypeError: cannot unpack non-iterable numpy.int64 object

[Peter-of-Astora]

Hello! This error comes from the Class "IdsGameEnv", in the function "step". And it is in this line:
attack_action, defense_action = action

And I am wondering what is this line used for, and how can I solve the problem.

Thank you!( •̀ ω •́ )✧

Hi, this library is not actively maintained. You can still use it but you need to fix import errors yourself, i.e. upgrading the dependencies. For an up-to-date library, see: https://github.com/Limmen/csle
