Hi,
I have a library (XGBoost) that is optimized for matrix manipulation and
hence I need to port my input (read from avro) `TypedPipe` to a matrix. I
am able to map each avro record to an array of floats. But I don't know
what to write as the fields in `toMatrix` arguments List
I am doing something like
private val inputData =
> TypedPipe.from(PackedAvroSource[SomeAvroRecord](args("inputData")))
.map(avroToFloatArray)
.toMatrix(....
Any help would be great.
Thanks,
Nikhil
