Hi all , I am trying to scale the my computation with koalas (instead of pandas). I have a class and I try to apply one of the function from the class on a dataframe two columns. With pandas df it works as expected, but when I do with koalas df, it throws the error ```Could not convert <__main__.XYZ object at 0x7f7746dfbef0> with type XYZ: did not recognize Python value type when inferring an Arrow data type``` I share the notebook which has class definition and computation with both of way. Error is in cell (13). Do you have any idea which are has a bug (koalas or arrow) ?
