Hi @yratof, sorry for the slow reply, I was away. What OS are you using, and how did you install or-tools?

Thanks

macOS and via pip. Possibly attempted via brew too, but I don’t believe had any luck finding it

Hmm, that should work (I'm using the same setup) -- might be a version mismatch.

What do you get if you run pip freeze | grep ortools?

Here's my output:

~/Projects/penkit/optimizer: pip freeze | grep ortools
ortools==6.7.4973
ortools-examples==6.4.4495

[yratof@eve:~] % pip freeze | grep ortools 1 ↵ ortools==6.7.4973 Looking like the same version
