have the same issue with Deeplearning Extension. I tried CUDA 10.1 as described in the marketplace. Tried also latest CUDA Version 11, still not working. Cudnn 7.6 ist installed. Unfortunately I have an urgent requirement ...

I think I found a solution for the issue. ND4J calls CUDA, so installing the latest CUDA toolkit seems to solve the issues. Here is a reference URL:
