Issue in Running Default Code

[Sfigaman]

Hi, i just downloaded the .zip of the code, installed all the dependencies and tried running the code.

I get this error:

Hi,
Thanks for taking interest!

There is probably something wrong with the new version of ortools (9.12.4544) that got released yesterday. I too faced the same error. I will try to investigate this.

In the meantime, try uninstalling the latest version pip uninstall ortools and reinstall a prior version pip install ortools==9.11.4210. That should do the trick.

Btw this is a hard sbc, so to get a solution quickly, try enabling the filter in main.py (L41).

Edit: This is definitely a issue with ortools.
