I am using mlr3 'fast nearest neighbor' leaner i.e. fnn
Its parameter is 'k' which has a default value of 1. When I use tuning
using random search, I set the parameter of k as: lower= 0, upper=3
But it gives an error message
Error in self$assert(xs) :
Assertion on 'xs' failed: k: Element 1 is not >= 1.
I have tried different values but the error remains.
Warm regards
