Code implementation of "Learning Efficient Online 3D Bin Packing on Packing Configuration Trees". We propose to enhance the practical applicability of online 3D Bin Packing Problem (BPP) via learning on a hierarchical packing configuration tree which makes the deep reinforcement learning (DRL) model easy to deal with practical constraints and well-performing even with continuous solution space.

Dear authors:

I am trying to reproduce your experiments claimed in your ICLR paper. But I got an error "You must specify a action space", the whole error information can be found below. Would you mind please providing some helpful information for this?

I run the command listed in README.md

python main.py

I have not encountered this error when using gym, maybe we are using a different gym version, the version I am currently using is gym==0.13.0

Thanks for your reply! The issue has been addressed by downgrading the gym package to 0.13.0. Thx.
