Hello.
I'm trying to use GPU in VOXL platform through opencl. So I followed `voxl-docker-opencv-opencl` [README](https://gitlab.com/voxl-public/voxl-docker-images/voxl-docker-opencv-opencl).
I am able to use opencl lib with VOXL1. But It didn't work on VOXL2 like below.

Any advice for this?
Thanks~

You only need the Docker on VOXL 1 if you want to use Debian OS 

VOXL 2 has Debian native so you don't need the Docker

Both platforms have opencl libraries in the native OS and do not require a Docker for OpenCL
