Hi all, I have a DataFrame that contains a user defined type. The type is an image with the following attribute
*class Image(w: Int, h: Int, data: Vector)* In my DataFrame, images are stored in column named "image" that corresponds to the following case class *case class LabeledImage(label: Int, image: Image)* How can I select image.data attribute of my image object and view it as a column of a DataFrame ? I'd like to do something like *val featureDF = imagesDF.select("image.data").as("features")* Cheers, Jao
