> When using functions from the LibMatrixDNN in a Spark ParFor block an exception is thrown by the function `warnSingleThreaded()` due to single threaded execution of functions such as conv2d. 
> Disabling this warning resolves the crash but I am not sure this is the right way to go there. The question is also why this executes with one thread only and how to improve here.
