How can I use this toolkit to do multi-output regression?

[offchan42]

For example, I have a bunch of real numbers (camera image from headset) as input and I want to predict where my left hand is relative to the camera (4 numbers, x, y, z, length).
My left hand will be visible on the camera.

x,y,z is a unit vector representing direction from camera to the left hand, and length is the distance from the camera to the left hand.

So can this tool support predicting multiple outputs? If yes, how could I do it?
If not please suggest me a tool that can do it or another way of solving my problem.
