Not to display the solver not found logs

[SanPen]

I have ortools as a dependency on a python program, and every time I run the program this shows:

Is there a way to turn these off?

[lperron]

do not ask for these solvers.

[lperron]

actually,

from ortools.init.python import init

then once: init.CppBridge.init_logging("my message")

[SanPen]

Thanks! this is it. I need to ask for the solvers to offer them in the GUI, so this helps.

Hi @lperron ,

the line of code init.CppBridge.init_logging("my message") blows up under windows 10/11, python 3.10, 3.11 at least and ortools version 9.10.4067. Under Ubuntu 22.04 it is ok.

https://github.com/google/or-tools/releases/tag/v9.10

read the known issues.

I'm not sure I see this one there, but my take is that we should not upgrade yet and have that reflected in our requirements.txt
