Model.fromFile(model) error #7

Closed isaaclo97 closed 4 years ago

isaaclo97 commented 4 years ago

I am trying to load models, it compiles correctly instead when executing it gives an error with Model.fromFile. I tried load a basic PMMLs to avoid file problems and it gets the same error.

Scala version: 2.12.11 Flink version: 1.9.2 Tested versions of pmml4s: 0.9.3, 0.9.4, 0.9.5

Any idea?

@isaaclo97 Different scala versions (2.11, 2.12, and 2.13) are not compatible. Since you use Scala 2.12, make sure you use pmml4s_2.12, which build tool is used? sbt, maven, or others?

@scorebot i used sbt and pmml4s_X.XX according to scala versions used, the problem was solved. The problem appear when i run it in local cluster with flink, when i run it with sbt run it does not appear.
