Hi! Try to reproduce example from tutorial http://gnpalencia.org/optbinning/tutorials/tutorial_binary.html#Basic and faced with the same issue as described in issue #208 at the moment of optb.fit(x, y) optbinning Version: 0.17.1 macos Ventura 13.0.1 solver="cp" full text of error [libprotobuf FATAL google/protobuf/message_lite.cc:352] CHECK failed: target + size == res:

Hi Daria.

AFAIK, this is an OR-Tools issue with macOS (> 12). All unit tests passed with macOS-12 link, so it might be an issue with macOS-13. On the other hand, OR-Tools wheels are not available for macOS 13: https://pypi.org/project/ortools/#files.

I would suggest:

• try solver="mip" and see if you experience the same error.
• contact ortools and describe this error with macOS-13. https://github.com/google/or-tools/issues

Hi! Thank you so much for your help. You are right, issue with macos-13, in linux/colabe everything is fine) Solver unfortunately didnt help. Regarding ortools - will have a look (didnt know anything about it).
