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
