This possibly seems an issue with SCIP installation/paths .
As mentioned in README, we request you to install SCIP and other dependencies, follow the instructions of https://github.com/ds4dm/learn2branch/blob/master/INSTALL.md
The bug is not directly associated with the current repo.
The instructions in the above link should help you in installation.
