Will this not impact @kcelia's PR where she needs to set MONO so CP doesn't crash ?

[fd0r]

I'm guessing this mono/multi issue only affects KNN so she can just set MONO in KNN dedicated test suite no?

[RomanBredehoft]

ah yes forgot to mention, this will conflict a bit with @kcelia's PR as I indeed removed force_mono_parameter_in_configuration (which she needs to use)

so either I wait for her the merge and then I rebase on main (which I think is best), or I put back the function with #pragma: no-cover in it (else pylint will probably complain that it's not used) cc @andrei-stoian-zama @fd0r

Nice clean up! I thought KNN was still needing mono params tho?

[kcelia]
