Hi, whenever I try to run vl_compilenn using gpu using MatConvNet toolbox the below error comes.
Config : cuda-10.1, cudnn-7.6.5, matlab2020a, visual studio 2015

It looks like 'vl_compilenn' is from a third-party repo called 'MatConvNet' which has its own forums. You can try looking for a solution there.
