How exactly should the “iter” parameter be used in the Scala API’s eval function? The documentation says “current eval iteration,” but I’m not completely sure what that means.
[jvm-packages] Iter parameter in eval function
The iter parameter should be set to the integer representing the number of rounds that have run so far. The parameter is really for print formatting, so if you don’t have this number handy, you can just supply 0.
