Hi @xtjjyygy,
We'd also love to provide this feature, but there we would need to deep copy a SCIP object, which is not possible right now.

@AntoinePrv Thank you for your reply, I've tried writing __ deepcopy__ Method to copy multiple inherited classes, but ecole core. scip.Model class No constructor defined，Very frustrating. I wonder if you have a detailed plan to develop this feature. If it is convenient, I can also participate in the development of this feature. Thank you again!
