Hello, I am sorry but after settings the value of C between 1 and 7, I get
the following error message now:
Error in self$assert(xs) :
Assertion on 'xs' failed: The parameter 'C' can only be set if the
following condition is met 'type <U+2208> {eps-svr, eps-bsvr}'. Instead the
parameter value for 'type' is not set at all. Try setting 'type' to a value
that satisfies the condition.
I have set the parameter values as following:
search_space = paradox::ParamSet$new(
params = list(paradox::ParamInt$new("C", lower = 1, upper = 7)))
