Questions about CUDA and cuDNN versions for Deep learning extensions.

Hi, RapidMiner.   

First of all, thank you very much for making such a great operator.

But I have a problem using the Deep learning extension.

The protocol using the deep learning operator of the Deep learning extension works well when the deep learning backend is set to the CPU, but when the deep learning backend is set to the GPU, it rarely uses the GPU. We also found that the computational speed was also slower than when we set backend with the CPU.

My graphics card is GTX 1080 Ti, CUDA version is 9.0.176, cuDNN version is 7.0. We have also set the environment variables for cuDNN.

Have I missed anything?  I know you are busy, but I need help. :'-(

Thank you.

Kim.
